Good question. I'm an absentee owner until we move in 3 years. I put up a life ring and rope last year. It's hanging on a 4x4 post next to the dock...and 3 feet away is another 4x4 post with a "No Trespassing" sign and a "No swimming, boating or fishing" sign. There are 2 other posts with signs on them around the pond as well. I still worry sometimes.
