I actually have a neighbor where i hunt that is very simular except he doesnt steal things. I still havent figured out how to deal with him, i just try to ignore him, but it can be so frustrating when he intentionally interrupts hunts or trys to block my trails. if i was you i would try to catch the guy trespassing, put IR camera up where he cannot reach it, or spend more time watching for him. whatever you do i wouldnt let him get away with it
