make sure he doesn't have a gun with him and call him a mother f**ker to his face. Tell him your done with him as a "hunting" buddy. You might loose a friend, but now days, having access to private land, and being able to harvest is becoming a premium. I have no issue calling some former friends mofo's after they pulled the same crap with me. Hermit trolls like me don't have friends anymore because of friends like that...
