If I go to Disney World, and, being a curious person, see something interesting and wander into an unmarked restricted area while checking it out. Have I committed a crime? There were no doors, no locks, no signs to tell me that this area was restricted. Just because it wasn't on the map and may have not had a clearly marked entrance, doesn't mean that I should have known it was a restricted area. Most criminal tresspass laws require at least clear signage or a previous communication, and even then, the area has to be clearly defined. You can't just wave your hand and say 'if you go over there, you're tresspassing' There are some large(20,000+ acres) areas near me that are used as ATV playgrounds. The ATV riders are not authorized to be there, and the land owners have taken some steps to put up signs. They are not consistent or ubiquitious, and the properly lines are not clearly marked or identified. Being that the area is not surveyed, law enforcement is very reluctant to charge anyone with criminal tresspass because they can't even tell themselves where the legal property lines are. Imagine trying to convince a jury beyond a reasonable doubt?
