When I was at DNR, Those scumbags were always getting run out of The State Forests. They'd set up camp up on an old landing up there and claim "Squatter's Rights" or "Rights under the Homestead Act." Or some other such BS.
In every instance they were run out of there for the exact same reasons:
Showing up on someone ELSE's land, scattering junk and garbage around, traffiking stolen goods, crapping openly wherever it suited them (picture Cousin Eddie from Christmas Vacation only 100lbs skinnier in the 'sh*tter's full!' scene), and using the land as thier own private hunting ranch and then getting hostile and refusing to leave when confronted.
