It doesn't matter about the buoys anyway, the "lake lice and ski boats" will ignore them. " Cranking" in Robinson Creek last year,I watched 2 different boats pulling little kids on tubes. They were running them around in about 4 to 5 feet of water with no telling how much stuff in the water. This was about a 1/4 mile past the buoy markers. I sat and prayed hoping they wouldn't fall off. Scared me to death. About the time I was going to run over to them they took off out of there. Lots of "idiots" out there !!!!!
