Sorry to hear your predicament. I am willing to bet they know the bank owns it and that you do not have exclusive rights to hunt it. This, of course, is not reason for them to use your stands. Your in a real bad situation that I would do my best to find anther place to hunt. Although, I do like the idea of squirrel hunting and doing your best to ruin there hunts...it will eventually get the point thru if you do it enough because they are traveling pretty far to hunt. Maybe then they might wanna talk to you.
