If you go to Delta Wakeboard Camps to ride I heard they have some. Otherwise most people keep them on the DL and hidden. For fear of people getting hurt and sheriffs pulling them out.
i found a few near orwood some out in open some hidden we wanted to get the hidden ones out but it was to swallow to tow them out some with a boat i need more hands or a waverunner. I really want to hit some up. any more ideas
