In this appeal, defendant Jose Castillo asks us to hold that his conviction for vagrancy cannot withstand an attack on the constitutionality of the underlying statute. Castillo was convicted in October of 1976 before a Magistrate in the Panama Canal Zone for violating one section of the Canal Zone Code’s vagrancy statute and for tampering with a motor vehicle, and given concurrent sentences of thirty days. After a trial de novo held without a jury, the judge for the District of the Canal Zone rejected Castillo’s constitutional challenge to the vagrancy law, found him guilty of both charges, and approved the concurrent sentences previously imposed. 1 We find no *406 constitutional infirmity in the vagrancy statute and therefore affirm the District Court.
Castillo was arrested on October 7, 1976, in a residential neighborhood in the Canal Zone. At the trial, one witness testified that at approximately six o’clock in the morning, she saw Castillo attempting to gain access to a truck in a garage adjacent to a private home, and a second witness testified that Castillo attempted to open the doors to a second house and to a vehicle parked in the street. Castillo was convicted for tampering with a motor vehicle under 6 Canal Zone Code § 1565(a)(3) but does not appeal from this verdict or sentence. This appeal is from the concurrent sentence imposed for Castillo’s conviction as a vagrant under 6 Canal Zone Code § 2541(1). The sole basis for reversal urged here is that the vagrancy statute is unconstitutionally vague and therefore void under the Fifth Amendment due process requirements.
Before considering this claim, we must resolve two aspects of this case that may moot the appeal. The first question is whether the fact that Castillo has long since completed his thirty-day jail sentence moots his appeal from the vagrancy conviction. In
St. Pierre
v.
United States,
1943,
We find that there is sufficient possibility that Castillo could suffer collateral consequences from his vagrancy conviction to justify our reaching the merits of this appeal despite the defendant’s satisfaction of his sentence. Castillo’s conviction under some circumstances “presumably could be used for impeachment and sentencing purposes in any future criminal proceeding,”
United States
v.
Camil,
5 Cir., 1974,
The second basis on which this case may be vulnerable to dismissal arises from the fact that Castillo was convicted under two counts and given concurrent sentences, but appeals from only one of the convictions. Even if we were to hold that the vagrancy conviction must be reversed, the defendant’s term of imprisonment would be unaffected. Under the concurrent sentence doctrine, this Court has the discretion not to reach the defendant’s challenge to the vagrancy conviction by reason of a valid (here, unchallenged) conviction and concurrent sentence on a separate count.
See, e. g., United States v. Bynum,
5 Cir., 1978,
The section of the Panama Canal Zone vagrancy statute challenged here, 6 Canal Zone Code § 2541(1), provides that:
Whoever:
(1) is found within or loitering about a building or structure, or a vessel, railroad car, or storage yard, without authority or permission so to be or to do so; . is a vagrant, and shall be fined not more than $100 or imprisoned in jail not more than 30 days, or both.
The constitutionality of this provision must be tested under the standard enunciated in
Papachristou v. City of Jacksonville,
1972,
void for vagueness, both in the sense that it “fails to give a person of ordinary intelligence fair notice that his contemplated conduct is forbidden by the statute,” United States v. Harriss,347 U.S. 612 , 617,74 S.Ct. 808 ,98 L.Ed. 989 , and because it encourages arbitrary and erratic arrests and convictions. Thornhill v. Alabama,310 U.S. 88 ,60 S.Ct. 736 ,84 L.Ed. 1093 ; Herndon v. Lowry,301 U.S. 242 ,57 S.Ct. 732 ,81 L.Ed. 1066 .
We emphasize at the outset that the provision at issue here bears little resemblance to the ordinance declared unconstitu
*408
tional in
Papachristou,
which “ ‘Derived from early English Law’ ” and therefore employed “ ‘archaic language’ ” in defining vagrancy.
The Panama Canal Zone statute has twenty-seven sections in all, many of which are identical to the language held unconstitutional in Papachristou. 5 Because Castillo *409 was charged and convicted only under the first section of the statute, we do not here rule on the validity of the remaining twenty-six provisions. We mention these provisions to emphasize the structure of this statute, which classifies a variety of crimes as vagrancy but then describes in more or less specific terms the conduct that is to be punished. See, for example, section 20, which prohibits indecent exposure; section 25, which proscribes carrying certain kinds of weapons; section 24, which forbids the possession of burglary’s tools; and section 27, which proscribes disorderly conduct. This structure also distinguishes the statute from the undifferentiated proscriptions involved in Papachristou.
The offense under section one of the Panama Canal Zone vagrancy statute has two elements: (i) that the defendant is “found within” or is “loitering” about a building, structure, vessel, railroad car, or storage yard, and (ii) that he have no authority or permission to be in such locations. Under the first part of the
Papachristou
vagueness test, we must determine whether these prohibitions are stated with sufficient precision to give a reasonably intelligent person notice of the conduct that is forbidden. See
Lanzetta
v.
New Jersey,
1939,
The language of the first element is readily distinguishable from that of the ordinances held invalid in
Papachristou, Powell v. Stone,
and
Newsome
v.
Malcolm.
In these cases, the offending ordinances provided that “persons wandering or strolling around from place to place without any lawful purpose or object . . . shall be deemed vagrants,”
Papachristou, supra,
a citizen who sought to conform his conduct to this provision would be unable to discern whether he risked criminal responsibility by taking a leisurely stroll, by sitting briefly on a park bench, or by seeking shelter from the elements in the doorway of a building.
In contrast to these vague and uninformative proscriptions, the Panama Canal Zone statute describes with relative specificity the places where an individual runs *410 the risk of criminality. The terms “found within” and “loitering” are still troublesome in their vagueness and potentially broad, unpredictable application. However, we find that the second element of the offense under the statute adds sufficient specificity to satisfy the Constitution.
Under the second element of the vagrancy offense established by this statute, the mere presence of an individual in a “building or structure, . . . vessel, railroad car, or storage yard” will not make him vulnerable to a vagrancy charge unless he has no “authority or permission” to be there. This language is free from the defects that appellate courts have found in clauses similarly designed to narrow the scope of vagrancy and loitering ordinances. In
Newsome v. Malcolm,
the second element of the loitering offense was established by “circumstances which justify suspicion that [a person] may be engaged in or about to engage in crime,”
An individual found in one of the enumerated places is vulnerable to arrest and conviction for vagrancy only if the circumstances show that no authorization or permission to be there was given by one who is capable of furnishing such consent. 6 The statute thus furnishes a single standard for criminality that is capable of objective ascertainment in each case. A reasonably intelligent person would, we believe, know that this statute forbids what are essentially acts of trespass: the presence in places to which access is obviously not open to all without permission or consent from those authorized to give it. 7 We decline to hold the law unconstitutional because Congress has chosen to label such conduct as a form of vagrancy rather than adopting a different formal classification. 8
When viewed as a variation on a trespass statute, this law does pass constitutional
*411
muster. The words “authority or permission” in the context of a trespass prohibition can have only one meaning: right, permission, or license recognized by law as permitting an entry into the areas described in the statute. See
Hurley
v.
Hinckley,
D.Mass., 1969,
The root of the vagueness doctrine is a rough idea of fairness. It is not a principle designed to convert into a constitutional dilemma the practical difficulties in drawing criminal statutes both general enough to take into account a variety of human conduct and sufficiently specific to provide fair warning that certain kinds of conduct are prohibited.
Colten v. Kentucky,
1972,
AFFIRMED.
Notes
. Castillo’s offenses both fall within the “exclusive original jurisdiction” of the Magistrates’ Courts as defined in 3 Canal Zone Code § 171(2): “Criminal actions wherein the punishment which may be imposed does not exceed a fine of $100, or imprisonment in jail for 30 days, or both.” Under 6 Canal Zone Code § 3921, a defendant can appeal from the Magistrate’s Court to the District Court, and, under § 3924, receive a trial de novo. The Canal *406 Zone Magistrate is an appointee of the President or his designee, 3 Canal Zone Code § 82, and is not a United States Magistrate under 28 U.S.C. § 631.
. It also appears that because Castillo “could not have brought his case to this Court for review before the expiration of the sentence,”
Sibron,
supra,
. The fact that Castillo was simultaneously convicted for a separate offense is irrelevant to the requisite possibility of consequences collateral to the sentence for vagrancy. See
Sibron, supra,
. The Jacksonville ordinance challenged in Papachristou provided that:
“Rogues and vagabonds, or dissolute persons who go about begging common gamblers, persons who use juggling or unlawful games or plays, common drunkards, common night walkers, thieves, pilferers or pickpockets, traders in stolen property, lewd, wanton and lascivious persons, keepers of gambling places, common railers and brawlers, persons wandering or strolling around from place to place without any lawful purpose or object, habitual loafers, disorderly persons, persons neglecting all lawful business and habitually spending their time by frequenting houses of ill fame, gaming houses, or places where alcoholic beverages are sold or served, persons able to work but habitually living upon the earnings of their wives or minor children shall be deemed vagrants.”
. Sections 2-26 of the Panama Canal Zone vagrancy statute read:

. Because this appeal resolves only the facial constitutionality of the statute, we do not address such questions as the sufficiency or burden of proof.
. The defendant’s conduct not only comes within the terms of the statute when understood as a prohibition against trespass, but also illustrates the clarity of these terms and the warning they provide. A reasonably intelligent person would understand that the premises of a private dwelling and the adjacent buildings, such as a garage containing a locked automobile, are buildings or structures within the meaning of the statute. And it is clearly reasonable to expect a person to know that no one has a right to be on the premises of a dwelling place without securing the permission of the occupant.
Used in this context, “loitering” is not a constitutionally bad word. It merely forbids the presence, whether standing still, shuffling, or sitting, on the premises of a dwelling, unless permission has been obtained.
