RE: Tough decision as a land owner.....
Your land, your rules. If they can't comply with them then they have no rights to be hunting there. I have some first cousins that inherited several hundred acres of prime hunting land. They won't let anybody hunt there, they won't even consider leasing the land to me and as far as I know there has never been any problems within the family. While I am very family oriented, but there are a number of my cousins, etc that if I don't see them again I won't lose any sleep over it.
