In Smith v. Arizona Bd. of Regents, 195 Ariz. 214, P9, 986 P.2d 247, P9 (App. 1999), the court held that the definition did not encompass a "jumping apparatus consisting of a combination of a trampoline and bungee cord" temporarily placed on a college campus during a carnival-like event. 195 Ariz. 214, P3, 986 P.2d 247, P3. The court stated that the legislature's intent in enacting the statute "appears to be to encourage accessibility and use of outdoor, open spaces for recreation" and that the types of structures the statute encompasses seem to "have some relation to the usual use of the property." Id. at P17.
