My buddy and I experienced some of these problems back a few years ago and it was at his boat slip at Six Mile. I went to Radio Shack and got these motion detectors that work off of a key remote and if you get up in the boat the alarm goes off if you don't hit the remote before. It was right at 60 bucks for two alarms and they worked. The neighbor heard the alarm go off one evening called the cops and went to the slips and one neighbors boat was sinking (pure vandlism)but they were caught before they could even get back across the creek. Good work Forsyth County. Across in the woods there was many fishing rod & reels found, a canoe and many other items. We got our things back as well.
