I get my thrills, from what I find in the ground, not proving I have a right to be hunting in places, that would most likely make some people uncomfortable. Mostly, I do curb strips and medians, which are more or less considered public property, least public access, and tolerated by most. I pass up areas where people take more interest in their little strip, and those where children are present. No parent should have to rush their kids indoors, while some stranger is loitering in front of their house.
Never really felt comfortable hunting at or near schools, it's only a hobby, and plenty of hassle free places to hunt. Schools have someone maintaining them, who probably wouldn't appreciate seeing someone, potentially making work for them. School officials are concerned about many things, safety and security being one. They just see a stranger on school grounds, who isn't involved in an official, school related activity. Sure, you are only enjoying a hobby, but they don't know what other hobbies you might have, or what other intention you might have. Central Florida seems to attract child molesters, so adults hanging around areas where children play, attracts a lot of attention. Parents need to be specially attentive at the theme parks, never letting their children out of sight for a moment.
There will always be locations, we view as potential gold mines, but know someone else is going to be upset over our being there cashing in. I know it hurts, but sometimes you just have pass these places. You got set your own rules and limits, otherwise the government will do it for you. Most laws aren't passed, unless people express an interest or concern. If we don't create a problem in the first place, no one is going to care enough to push legislation to ban or limit our hobby.
