Post a sign in front of the trees. PRIVATE PROPERTY, TRESPASSERS WILL BE SHOT.Most people really do not realize that it is stealing if they are very far from your house.At one time I managed apts in Newnan, ga with beautiful, I think it was plum trees down near the road, one day I noticed a guy picking them and walked down and asked him if he knew he was stealing, and he said no since they were so close to the road, told him he better go or I would call and have him arrested, Posted sign, no more problem. marrie
