Doris Diamond brought a negligence action against the Springfield Metropolitan Exposition Auditorium Authority (“SMEAA”), the owner and operator of a public convention center located in Springfield, Illinois, claiming she suffered physical injuries as a result of a fall at the SMEAA’s convention center. The district court granted the SMEAA’s motion for summary judgment, ruling that Diamond’s claim was barred by the Illinois Local Government and Government Employees Tort Immunity Act (“Tort Immunity Act”), 745 ILCS 10/3-106. We affirm.
I.
The SMEAA owns and operates the Prairie Capital Convention Center in Springfield, Illinois, a multi-purpose facility used for meetings, shows, expositions, rodeos, boxing *601 matches, wrestling events, basketball games and tournaments, karate tournaments, and other public events. The SMEAA was created pursuant to sections 205/3 and 4 of the Metropolitan Civic Center Act, 70 ILCS 205/3 and 4, which authorized counties or groups of counties to form authorities to promote, operate, and maintain expositions, conventions, theatrical, sports and cultural activities. The SMEAA is authorized by statute to plan, sponsor, hold, arrange, and finance fairs, exhibits, shows, and events.
It shall be the duty of the authority to promote, operate, and maintain expositions and conventions from time to time in the metropolitan area and in connection therewith to arrange, finance and maintain industrial, cultural, educational, trade and scientific exhibits and to construct, equip and maintain auditoriums and exposition buildings for such purposes. The authority is granted all rights and powers necessary to perform such duties.
70 ILCS 345/4; see also 70 ILCS 345/5(b).
Diamond was injured on July 9,1993, while she was on her way to attend a career-related conference for sexual abuse counsel-lors at the Convention Center. Diamond tripped in the doorway to an underground tunnel leading to the Convention Center. In her negligence action against the SMEAA, Diamond alleged that she sustained broken bones and other permanent physical injuries as the result of her fall.
The SMEAA moved to dismiss 1 Diamond’s complaint, asserting that it was immune from liability for negligence under section 3-106 of the Tort Immunity Act, which provides that
[njeither a local public entity nor a public employee is liable for an injury where the liability is based on the existence of a condition of any public property intended or permitted to be used for recreational purposes, including but not limited to parks, playgrounds, open areas, buildings or other enclosed recreational facilities, unless such local entity or public employee is guilty of willful and wanton misconduct proximately causing such injury.
745 ILCS 10/3-106. The SMEAA contended that Diamond’s injuries occurred on “public property intended or permitted to be used for recreational purposes” within the meaning of the Tort Immunity Act. To support its motion, the SMEAA filed an affidavit by Judith Meiron, the General Manager of the Convention Center, which stated that
[t]he Prairie Capital Convention Center is property intended or permitted to be used for recreational purposes. Recreational activities which have been permitted on the premises in the past include, but are not limited to, City basketball tournaments, World Wrestling Federation events, rodeos, boxing matches and karate tournaments.
Diamond opposed the SMEAA’s motion, arguing that the Tort Immunity Act did not preclude her suit because the Convention Center could not be characterized as a recreational facility within the meaning of the Act and because her purpose for visiting the Convention Center had nothing to do with recreation.
The district court entered summary judgment in favor of the SMEAA, ruling that section 3-106 of the Tort Immunity Act barred Diamond’s claim. The court observed that “[t]he determinative question in this case is whether the Prairie Capital Convention Center is public property intended or permitted to be used for recreational purposes,” and thus “the question is what is the character of the Convention Center, not why was Plaintiff at the Convention Center.” .The court found that
[t]he Convention Center is a building which provides the people of Springfield and surrounding areas a place to hold public events. A great many of these events are recreational in nature. Even if some of these events are not strictly recreational, they are still examples of members of the community being offered available space to help facilitate their needs. The development and maintenance of buildings like the Convention Center should be en *602 couraged. Since the Convention Center is used for recreational purposes a large percentage of the time, the Court concludes that for the purposes of section 3-106 the Convention Center is public property intended to be used for recreational purposes.

We review the district court’s grant of summary judgment
de novo,
drawing all reasonable inferences from the record in the light most favorable to the non-moving party.
Donovan v. City of Milwaukee,
The sole issue raised by this appeal is whether section 3-106 of the Tort Immunity Act immunizes the SMEAA from liability for negligence in its operation of a public, multipurpose convention center. Our determination of this issue turns on the proper interpretation of the phrase “public property intended or permitted to be used for recreational purposes” in section 3-106 of the Tort Immunity Act. This case presents a question of Illinois law that to date has not been addressed by the Illinois Supreme Court. Our duty is to determine, as best we can, how this dispute would be resolved by the Illinois Supreme Court.
Todd v. Societe BIC, S.A.,
Section 3-106 of the Tort Immunity Act provides immunity to local public entities against negligence claims arising from “the existence of a condition of any public property intended or permitted to be used for recreational purposes.” 745 ILCS 10/3-106;
Hanover Ins. Co. v. Board of Education,
Diamond argues that the Convention Center is neither “intended [nor] permitted to be used for recreational purposes” within the meaning of the Tort Immunity Act because the recreational activities held at the Center — including basketball tournaments, wrestling events, rodeos, boxing matches and karate tournaments — are all spectator events. One Illinois court has held that a facility that was used for a spectator event on one occasion cannot be characterized as recreational property within the scope of section 3-106.
See, e.g., John v. Macomb,
From the record it cannot be determined whether “Heritage Days” is a recreational use of the courthouse lawn. Nor does the record disclose whether defendants customarily permitted any recreational activity on the lawn. The record indicates that on the night in question a band played. But permitting a band concert, without more, does not so alter the character of a public area not generally used for recreational activity that it would necessarily fall within the intended scope of section 3-106 of the Act. In our opinion, the legislative intent of the Act is to immunize governmental entities from liability for simple negligence in areas where public activities of a sportive nature, as opposed to stage entertainment, are permitted. Similarly, the record discloses that a concession stand was permitted on the premises. This is surely a business pursuit — not one that, in itself or combined with the proximity of a band concert, renders the grounds a recreational facility for purposes of section 3-106 of the Act.
John,
Unlike the defendant in
John,
the SMEAA presented the district court with uncontradicted evidence that the Convention Center had hosted several public activities of a “sportive nature” in the past, including city basketball tournaments, wrestling events, rodeos, boxing matches, and karate tournaments. These activities are not only “sportive” in nature, but recreational by definition. “Recreation” is synonymous with “diversion” or “play.” Webster’s Third New Int’l Dictionary 1899 (1981);
see also Frazier v. Norfolk,
Diamond also argues that section 3-106 immunity applies only to facilities used
primarily
for recreational purposes, and that the Convention Center’s primary use raises a genuine issue of material fact. In
Bubb v. Springfield School District 186,
*604
We decline to follow the Illinois appellate court’s construction .of section 3-106 announced in
Bubb.
We think it improvident to follow an intermediate state court’s interpretation of state law if we are convinced that the state’s highest court would decide the issue differently.
Robinson v. Ada S. McKinley Community Services, Inc.,
Moreover, with the exception of
Bubb,
Illinois appellate courts have consistently refused to consider the plaintiffs use of the property in determining its character.
See, e.g., Hanover,
The legislative history of section 3-106 supports this broad interpretation of the statute. Prior to its amendment in 1986, section 3-106 of the Tort Immunity Act applied only to public property “intended or permitted to be used as a park, playground or open area for recreational purposes.” Ill. Rev.Stat.1985, ch. 85, para. 3-106. In 1986, the legislature amended the statute to provide immunity for
“any
public property intended or permitted to be used for recreational purposes,.... ” 745 ILCS 10/3-106 (emphasis added). Amended section 3-106 still provided immunity for parks, playgrounds, and open areas, but added “buildings or other enclosed recreational facilities” to the illustrative list of immunized public properties.
Id.
In our opinion, the 1986 amendment to section 3-106 evidences the legislature’s intent to broaden the scope of immunity provided by the Tort Immunity Act beyond parks and playgrounds to encompass other properties where recreational uses are intended or permitted.
See Bonfield v. Jordan,
III.
Diamond’s- negligence claim against the SMEAA for its alleged failure to maintain the Convention Center’s underground tunnel in a reasonably, safe condition is barred by section 3-106 of the Tort Immunity Act because the Convention Center is “public property ... permitted to be used for recreation *605 al purposes” within the meaning of the Act. 4 The judgment of the district court is
AFFIRMED.
Notes
. We are of the opinion that the district court's action in treating SMEAA’s motion, including its affidavits in support of the motion to dismiss Diamond’s complaint, as a motion for summary judgment was proper. Fed.R.Civ.P. 12(b).
. We note that the Illinois Supreme Court granted leave to appeal in Bubb v. Springfield School District 186 on December 6, 1994 (Ill.Sup.Ct. No. 777-62).
. We note that this case does not require us to determine whether immunity attaches to public property permitted to be used for recreational purposes on a single occasion.
. We affirm the district court's conclusion that section 3-106 immunity applies, but in so doing, we find it unnecessary to comment on the court's reasoning that the Convention Center is public property intended to be used for recreational purposes. Section 3-106 grants immunity for public property "intended or permitted to be used for recreational purposes.” Because the Convention Center was dedicated to a number of uses, including recreational uses, we need not address the SMEAA’s argument that the Center was intended for recreational use.
