I see your point believe me. But being a responsible land owner in my eyes as well a friend to he hunting sports there is nothing I like more then sharing hunting opertunities with fellow sportsman. How ever the explanation I got when I finally caught up with one of the guys that was on my land " I let everybody and there brother on here but when they asked to bow hunt it in October I told them no". Our bow season starts in mid september. I have had people ask me in August for permission and have had to turn them away because I had people out there already. In there minds it was ok because I let other people out there. I guess to get back to the point is there are reasons that people may not let others onto there land. When I calm down from my experience I know that come next year there will be people out there that I have given permision. It is just upsetting and it is like someone is stealing from me. You are right though I should not let a few put a bad taste in my mouth about the restbut it is hard. One thing I might try is to talk to the land owner that your dad has permission to hunt the land from and explain that situation with your dad being crowded out of his hunting spot by another hunter and there is always the possibility that he/she can handle it. Good luck to you.
