I Had Some Fellows Always Looking For My Brush. So I Started Marking Them With Coke Bottles On A String For Them. Then After A Couple Of Weeks I Move The Bottle About 20 Yards. I Found That If They Are To Lazy To Build Their Own Brush Then They Are To Lazy To Hunt Around For The Brush. They Just Keep Fishing Around The Bottle That They Think Is Marking The Spot. Lol Doesnt Always Work But A Lot Of The Time It Does.
