Deer Hunting

Neighbor Problems

I hunt a small tract of land surrounded by a strictly managed hunting club. We are bordered by private landowners on our north side, who we used to allow to hunt our property before they purchased their land. Well, here lately they get angry every time i shoot a deer and ruin my hunt by walking or riding four wheelers on the property line(usually the first or last thirty minutes of the day). I am good friends with their sons and they seem to have no problem with me. But their parents are making hunting a living heck for me. To the point we dont share trail camera pictures anymore. They even offered to cut our small cabin lot for us while my dad was in the hospital then charged us fourty dollars once a week for three months. It really chaps my hind side, but I dont want a bad neighbor relationship, so any suggestions? We have already tried to approach them and ask them to stop and they got extremely defensive and confrontational. Any thoughts or advice is greatly appreciated.
