youngfart,
Those are all good suggestions. The problem with getting exclusive permission around here is, everyone is pretty much related in one way, and it is a small farming community; everyone knows everyone. I only have one of my neighbors that gives me exclusive deer hunting permission on his property, but I also help him out as soon as we are done with harvest, and lots of other odd jobs. I actually had another bowhunter call me last year and ask if it was OK if he hunted that property. The landowner told him he had to get permission from me! haha
