MEMORANDUM OPINION
Plaintiffs challenge the constitutionality of an amended United States Postal Service (“USPS”) regulation that prohibits collecting signatures for petitions, polls or surveys on certain USPS sidewalks, arguing that the restriction is overbroad because the regulation applies to a substantial number of postal sidewalks that are public forums. The parties conducted a survey of postal facilities in an attempt to quantify the extent of expressive activity on USPS sidewalks and have filed renewed cross-motions for summary judgment. Because material facts are not in dispute, the regulation no longer applies to exterior USPS sidewalks that are indistinguishable from public sidewalks, and the plaintiffs have not shown that the interior sidewalks to which the regulation still applies are public forums or that the regulation is unreasonable or void for vagueness, the defendant’s motion will be granted and the plaintiffs’ motion will be denied.
*30 BACKGROUND
The background of this case is set out in
Initiative & Referendum Inst. v. U.S. Postal Serv.,
Soliciting alms and contributions, campaigning for election to any public office, collecting private debts, soliciting and vending for commercial purposes (including, but not limited to, the vending of newspapers and other publications), displaying or distributing commercial advertising, soliciting signatures on petitions, polls, or surveys (except as otherwise authorized by Postal Service regulations), and impeding ingress to or egress from post offices are prohibited.
39 C.F.R. § 232.1(h)(1) (2002) (emphasis added). The underlined language, added in 1998, gave rise to this suit in which the plaintiffs challenge the regulation’s application to exterior postal property.
See IRI I,
Following the court of appeals’ decision, USPS amended § 232.1(h)(1) and it now states:
Soliciting alms and contributions, campaigning for election to any public office, collecting private debts, soliciting and vending for commercial purposes (including, but not limited to, the vending of newspapers and other publications), displaying or distributing commercial advertising, collecting signatures on petitions, polls, or surveys (except as otherwise authorized by Postal Service regulations), are prohibited.
39 C.F.R. § 232.1(h)(1) (2010) (emphasis added). USPS also modified § 232.1 such *31 that it no longer applies to “sidewalks along the street frontage of postal property falling within the property lines of the Postal Service that are not physically distinguishable from adjacent municipal or other public sidewalks, and any paved areas adjacent to such sidewalks that are not physically distinguishable from such sidewalks.” 39 C.F.R. § 232.1(a)(ii) (2010).
Also after the remand, the parties conducted a survey of selected postal properties to determine the type and extent of expressive activity that takes place on various postal sidewalks. They sent questionnaires to the facility manager at each retail post office in twelve postal Districts, 2 constituting 4,513 of the 32,621 retail postal facilities nationwide that existed at the time of the survey. (Def.’s Stmt. ¶¶ 22-23.) Seventy-nine percent of these surveyed postal facilities responded, yielding 3,566 completed questionnaires. (Def.’s Mem. of P. & A. in Supp. of Def.’s Renewed Mot. for Summ. J. (“Def.’s Mem.”), Decl. of Gregory M. Whiteman ¶ 12.) Although the “Districts selected are representative of postal Districts nationwide[,]” they “were not chosen on a statistical basis and therefore the survey was not designed to be a valid statistical representation of postal Districts nationwide.” (Def.’s Stmt. ¶ 23.) The survey divided postal sidewalks into four categories:
A.Sidewalks at the border of the postal property that are continuations of and/or indistinguishable from adjacent municipal or public sidewalks ....
B. Sidewalks within, but not at the border of, postal property that run along any side of the post office building....
C. Sidewalks that provide ingress/egress to the post office, ie. pathways from the street or parking lot to the front door....
D. Other
(Def.’s Mem., Ex. B., Postmaster Questionnaire ¶¶ 3, 10.) For each type of sidewalk, the survey asked about the type and frequency of expressive activity. 3 The survey instructed the facility manager to report not only on the manager’s current facility, but on all facilities that the manager had managed in the past. (Id. § 2.) There were 6,053 facilities in the final data set. (Pis.’ Mem. of P. & A. in Supp. of Pis.’ Renewed Mot. for Summ. J. (“Pis.’ Mem.”), Decl. of Joseph B. Kadane ¶ 3.) As to the ultimate number of sidewalks on which expressive activity took place, the plaintiffs assert that there are 518 records showing responsive activity (id. ¶ 4(e)), and USPS asserts that there are 562 sidewalks “where expressive activity was indieated[.]” 4 (See Def.’s Mem., Decl. of Gregory M. Whiteman ¶ 15.)
The plaintiffs have moved for summary judgment, arguing that the amended *32 § 232.1(h)(1) is facially unconstitutional because a substantial number of Kokinda 5 sidewalks are public forums, the regulation is not reasonable even if the Kokinda sidewalks are nonpublic forums, and the regulation is void for vagueness. 6 The plaintiffs also seek to enjoin USPS from applying the regulation to Grace sidewalks. USPS has also moved for summary judgment, arguing that the non-Grace sidewalks are not public forums, and that the amended § 232.1(h)(1) is valid because it is reasonable.
DISCUSSION
Summary judgment is appropriate where the record shows that “there is no genuine issue as to any material fact and that the movant is entitled to judgment as a matter of law.” Fed.R.Civ.P. 56(c)(2);
see also Moore v. Hartman,
Ordinarily, a litigant has standing to vindicate only his own constitutional rights.

I. FORUM ANALYSIS
Because “[n]othing in the Constitution requires the Government freely to grant access to all who wish to exercise their right to free speech on every type of Government property without regard to the nature of the property or to the disruption that might be caused by the speaker’s activities[,]” the Supreme Court has
*33
“adopted a forum analysis as a means of determining when the Government’s interest in limiting the use of its property to its intended purpose outweighs the interest of those wishing to use the property for other purposes.”
Cornelius v. NAACP Legal Def. and Educ. Fund, Inc.,
A. Grace sidewalks
When categorizing a sidewalk that bears “apparent similarity to ones of the classic variety[,]” the government bears the burden of overcoming the presumption that the walkways are public forums by showing that they are “overwhelmingly specialized.”
8
Id.
In
United States v. Grace,
Regulations may restrict the time, place, and manner of expressive activity in a public forum only if such regulations are content-neutral, narrowly tailored to serve a significant governmental interest, and
*34
leave open ample alternative channels for communication.
Perry Educ. Ass’n v. Perry Local Educators’ Ass’n,
USPS has made this very modification. The regulation no longer prohibits signature gathering on postal property consisting of
Grace
sidewalks.
See
39 C.F.R. § 232.1(a)(ii) (2010). Citing
City of Mesquite v. Aladdin’s Castle, Inc.,
“ ‘Federal courts lack jurisdiction to decide moot cases because their constitutional authority extends only to actual cases or controversies.’ ”
Matthews v. District of Columbia,
Here, unlike in
Aladdin’s Castle,
the plaintiffs have not produced any evidence that USPS intends to re-amend the regulation at the termination of this litigation to again prohibit signature gathering on
Grace
sidewalks. USPS’ changed position during this litigation as to whether the unamended regulation applied to
Grace
sidewalks
(see
Pis.’ Mem. at 6 n. 2) is not
*35
probative of any future intent to restore the previous language. The plaintiffs merely speculate that USPS could amend the provision at a later date, but such speculation is not sufficient to warrant the injunctive relief that they seek.
See Nat’l Black Police Ass’n,
B. Kokinda sidewalks
1. Overbreadth
The plaintiffs further argue that there are a substantial number of
Kokinda
sidewalks that also constitute public forums, rendering the regulation facially invalid even if it does not apply to
Grace
sidewalks. (Pis.’ Mem. at 6.) The Supreme Court conducted a forum analysis regarding a non-Grace postal sidewalk in
United States v. Kokinda,
Other courts also have analyzed the forum status of walkways at specific post office properties by considering their physical characteristics and their purposes.
See, e.g., Jacobsen v. U.S. Postal Serv.,
The most complete analyses of the forum status of postal sidewalks have not merely considered the character and purpose of the sidewalk in question, but also have evaluated the extent to which expressive activity historically has taken place on the property. These cases suggest that a specialized sidewalk intended to facilitate postal business could be a public forum if, historically, it had been the site for a sufficiently large amount of expressive activity.
See, e.g., Kokinda,
Here, the regulation at issue no longer applies to “sidewalks along the street frontage of postal property falling within the property lines of the Postal Service that are not physically distinguishable from adjacent municipal or other public sidewalks[.]” 39 C.F.R. § 232.1(a)(ii) (2010). Thus, the sidewalks to which the regulation still applies — which are by definition physically distinct from “classical variety” sidewalks — are not subject to the presumption that they are public forums.
Cf. Henderson,
At a minimum, therefore, a successful facial challenge to the amended regulation
*37
requires the plaintiffs to demonstrate that a substantial number of these sidewalks are public forums by pointing to their past usage as gathering places to promote “the free exchange of ideas.”
See Del Gallo,
However, even if it were possible to draw statistically valid conclusions from the parties’ survey, the data do not allow for any meaningful conclusion to be made about the historical regularity of expressive activity on
Kokinda
sidewalks. The survey asked postal managers about expressive activity on the sidewalks of the postal office that they currently manage and on the sidewalks of each postal office that they had previously managed. (Def.’s Mem., Ex. B., Postmaster Questionnaire.) Although the survey asked for the dates that the managers served at each postal facility, the managers did not provide the dates on which expressive activity occurred, nor do the parties’ experts draw conclusions about the dates on which reported expressive activity took place. These omissions prevent a determination that any of the various properties has been a site of expressive activity of sufficient historical regularity to be considered a public forum.
See Del Gallo,
Finally, the plaintiffs argue that “from a statistical standpoint, the
Kokinda
sidewalks in question were in fact indistinguishable from
Grace
sidewalks within the scope of the survey.”
13
(Id.
at 11-12 (emphasis omitted).) Even if the survey results allowed for the conclusion that there is no statistically significant difference between the observed frequency of expressive activity on
Grace
and
Kokinda
sidewalks — which the results do not allow for since the samples are not necessarily representative of the population of postal sidewalks — this argument would confuse the relevant inquiry. The plaintiffs point to no authority for the proposition that if the frequency of expressive activity on a particular type of property is comparable to the frequency of expressive activity on a public forum, the property in question must also be a public forum. Rather, the frequency of expressive activity on
Grace
sidewalks is immaterial to their status as public forums because they are physically indistinguishable from classical variety sidewalks.
See Henderson,
2. Reasonableness
The plaintiffs argue on remand that the amended regulation is unreasonable because it permits the solicitation but prohibits the collection of signatures on postal property, and because 39 C.F.R. § 232.1(e), a separate provision of the regulation, prohibits disruptive activity that would interfere with postal customers entering or leaving the property. (Pis.’ Mem. at 29-30.) “[T] he state may reserve [a nonpublic] forum for its intended purposes, communicative or otherwise, as long as the regulation on speech is reasonable and not an effort to suppress expression merely because public officials oppose the speaker’s view.”
Perry Educ. Ass’n,
The court of appeals held that the unamended regulation’s apparent ban on “pure solicitation — in the sense of
asking
postal patrons to sign petitions — even if the signatures themselves are to be collected off postal premises” was unreasonable but that construing the regulation not to prohibit “communications that promote the signing of petitions, polls, and surveys somewhere other than on Postal Service premises” would “cure the problem[.]”
IRI III,
Moreover, § 232.1(e) does not render the signature collecting prohibition in § 232.1(h)(1) unreasonable. It is reasonable for USPS to adopt a regulation that attempts to prevent disruption before it occurs.
See IRI I,
Additionally, because USPS is regulating speech in a nonpublic forum, it does not have to demonstrate that the regulation is narrowly tailored to the government interest it seeks to achieve.

II. VAGUENESS
The plaintiffs argue that the amended regulation’s language limiting its application to
Kokinda
sidewalks is vague in three respects: 1) “it provides no substance to the phrase ‘physically distinguishable,’ leaving it entirely to the discretion of the enforcing official[,]” 2) “it is unclear what sidewalks qualify as ‘along the frontage[,]’ ” and 3) it is unclear whether the exception “can encompass any non-perimeter sidewalks[.]” (Pis.’ Mem. at 31.) “It is a basic principle of due process that an enactment is void for vagueness if its prohibitions are not clearly defined.”
Grayned v. City of Rockford,
Here, the language about which the plaintiffs complain is not unconstitutionally vague when considered in the context of the regulation’s entire provision. It may be that the precise meanings of the phrases “physically distinguishable,” “along the street frontage,” and “adjacent to such sidewalks,” in isolation, are not apparent. However, these provisions are part of an actual sentence, and each of these three phrases serves to inform and provide context for the others: § 232.1(h)(1) does not apply to “sidewalks along the street frontage of postal property falling within the property lines of the Postal Service that are not physically distinguishable from adjacent municipal or other public sidewalks, and any paved areas adjacent to such sidewalks that are not physically distinguishable from such sidewalks.” 39 C.F.R. § 232.1(a)(ii) (2010). The plaintiffs argue that a crack, seam, or change in color in a
Grace
sidewalk could provide a basis for an enforcing official to not apply the exclusion to that sidewalk. But such minor physical anomalies are
*41
common to sidewalks generally and cannot alone serve to distinguish a
Grace
sidewalk from its “adjacent municipal [sidewalks] or other public sidewalks[.]”
Id.
By contrast, interior postal sidewalks and postal sidewalks perpendicular to adjacent municipal sidewalks, for example, are physically distinguishable from both adjacent municipal sidewalks and other public sidewalks because of their position relative to the perimeter of postal property. Moreover, the phrase “paved area” cannot provide a basis for an enforcing official to apply the exclusion to a
Kokinda
sidewalk that runs perpendicular to a perimeter sidewalk, as the plaintiffs argue, because the exclusion applies to sidewalks “along” the frontage, not perpendicular to it. The regulation therefore is not unconstitutionally vague when read in context.
See Grayned,
CONCLUSION
The plaintiffs have not shown a need to enjoin USPS from re-amending the regulation to apply to Grace sidewalks. Nor have the plaintiffs carried their burden to show that the amended regulation is over-broad, as they have not demonstrated that a substantial number of Kokinda sidewalks are public forums. Because no material facts are in dispute and the regulation is reasonable and not void for vagueness, the defendant’s motion [142] for summary judgment will be granted, and the plaintiffs motion [143] for summary judgment will be denied. An appropriate Order accompanies this Memorandum Opinion.
Notes
. In
United States v. Grace,
."The specific Districts were chosen to provide retail offices that would be reflective of urban, suburban and rural locales, office size and a geographic spread throughout the contiguous United States.” (Def.'s Mem. of P. & A. in Supp. of Def.’s Renewed Mot. for Summ. J., Decl. of Gregory M. Whiteman ¶ 3.) The parties sent surveys to the following districts: Greater South Carolina, Columbus, Philadelphia Metro, Greater Michigan, Central New Jersey, Connecticut, San Francisco, Atlanta, Central Florida, Rio Grande, Colorado/Wyoming, and Spokane. (Id. ¶ 4.)
. Expressive activities included soliciting signatures, leafleting, picketing, protesting, public gathering, and displaying signs. (Def.’s Mem., Ex. B., Postmaster Questionnaire ¶¶ 5, 12.) Frequencies included never, less than once per year, one to two times per year, three to six times per year, approximately monthly, and several times per month, in addition to "[djon’t know/ [u]nsure[.]” (Id. ¶¶ 6, 13.)
. The difference is not material to the analysis.
. See n. 1, supra.
. The plaintiffs' motion does not renew their challenge to the regulation as applied to the twelve exemplary post offices identified in the complaint. The plaintiffs' supporting memorandum refers to those post offices only for the purpose of supporting the plaintiffs' argument that the regulation at issue is facially unconstitutional.

did not disturb the holdings of
IRI I,
. The plaintiffs assert that this presumption applies to all sidewalks. (See Pis.’ Mem. of P. & A. in Opp’n to Def.’s Renewed Mot. for Summ. J. at 2-3.) However, the government bears the burden of showing that sidewalks are not public forums only for sidewalks of the "classic variety,”
Henderson,
. The plaintiffs do not refute USPS' claim that postal sidewalks are intended to facilitate *37 postal business. They instead merely dispute the legal implication of this fact. (See Pis.’ Mem. of P. & A. in Opp'n to Def.'s Renewed Mot. for Summ. J. at 4 ("At the heart of the government’s argument is an assumption that a sidewalk dedicated to some purpose cannot also be a public forum. But this Circuit’s decisions ... have explicitly rejected that argument.”).)
. It is also impossible to draw any statistically valid conclusions from the twelve exemplary post offices, which are not representative of post offices nationwide. (See Pis.’ Mem. at 15 (acknowledging that "the 'subject post offices' were selected precisely because plaintiffs and others had previously used their sidewalks for petitioning activities”).)
. With respect to the exemplary post offices, most of the evidence the plaintiffs cite similarly fails to distinguish between expressive activity that took place on Grace sidewalks and expressive activity that took place on Kokinda sidewalks. (See, e.g., Pis.' Mem. of P. & A. in Supp. of Pis.’ Mot. for Summ. J., Docket # 65, Ex. 34, Freeman Dewayne Lents Dep. at 31:4-9 ("Just a couple of weeks ago, we did have somebody that was soliciting signatures ... on the sidewalk[.]”); Ex. 35, Carol Bech *38 tel Dep. at 52:18-19 ("They were on the sidewalk in front of the post office.”).) The one deposition the plaintiffs cite that does distinguish between Grace and Kokinda sidewalks refers to expressive activity that took place on a Grace sidewalk, which is not relevant to determining the historical regularity of expressive activity on Kokinda sidewalks. (See id., Ex. 36, William C. Farrell Dep. at 23:21-22 ("Q: And where did you tell them to go? A: To relocate to the south public sidewalk[.]” (emphasis added)).)
. Even if the plaintiffs' assertion that "enforcement of the regulation has resulted in an observed reduction in expressive activity” (Pis.' Mem. at 10) is correct, the data do not reveal a baseline for comparison. Without knowing the historical frequency of expressive activity, the significance of the reduction cannot be determined.
. The plaintiffs draw this conclusion from the following data concerning expressive activity observed on various postal sidewalks:
[[Image here]]
.While the plaintiffs point to other anecdotal evidence in the record to argue that "[p]ost office sidewalks have long served as a principal public forum for all kinds of expressive activities” (Pis.’ Mem. at 7-10), none of this evidence distinguishes between Grace and Kokinda sidewalks. Because the plaintiffs cannot demonstrate with reasonable certainty that individuals have not confined their expressive activities on postal properties exclusively or even largely to Grace sidewalks, this evidence is insufficient to demonstrate that Kokinda sidewalks are public forums.
