I can't remember any squatters in our little area if there were it would be on the police report on the little local paper, and then the sheriffs and forest service law enforcement keep a pretty good eye on what's going on, in town it would be the same thing about the time some one complained they would be all over it, every now and then I will see a travel trailer out on some ones property it's usually given permission from the property owner or they own it. it's always good to keep an eye on things out of the ordinary. that's what's nice about not living in the big city. These guy's in the forest service in my area don't play around if you are in there for more than 14 days in a 30 day period you get a warning ticker in your camp, my understanding there are some exceptions . I do see very few people playing the game where they will move their RV or Trailer to another forest and return to start their time over. I get it.
