Have to agree... Some folks were getting PO'd the other day with people trapping and setting ground hogs free near/on other people's property...I hope none of them feel it is okay for a squatter to live on your land. I will say that if you squat on my land you will be shot on my land. Now the arson is bullchit... I will agree that he has a right to his possessions if he wants them.
This is my dream existence for post retirement. Off grid, living off what I grow and harvest for the most part. The difference is it would be on my own land.
Like all these folk that think college should be free for everybody. Ask them to contribute to the cost and see what you get.
