we live on 10 plus acres,all woods except where the house is. Two sides are adjacent to a hunt club,no problem. the other side is next to a campground.we post every year and somehow the signs nearest the campground get torn off. my lawyer says as long as the signs are gone i can not have trespassers arrested . I can only ask them to leave.i have approached the camp ground leaders to explain the rules to their members. they say they have talked and sent a letter out to each member.They also say that maybe they are strangers using campground property to enter ours. I have not hunted in years but most real hunters will respect others property.i have offered the hunt club to make a drive of my swamp .the deer seem to migrate there when the shooting starts. any ideas i can use to stop the trespassing would be appreciated thank you bob w.
