Post your line. Ask them to call before crossing the line. Meet them at the line and ask where was the deer standing & point of impact. I had a guy who was “tracking a deer” up into my treestand. Caught him a second time and I called the DEC. I requested that I the right to refuse him access for any reason and the DEC agreed and tracked him down. Trespassing is trespassing. They put others safety at risk.
I would love to walk through some of these trespassers backyards with a loaded 12 gauge.
