Always thought about perhaps taking one of those inflatable 2 man boats that you can paddle..... blowing it up, then paddle to the middle of a lake, anchoring the raft down, and camping out that way. I guess if did this in a lake that has boats in it, you would have to have a safety light so you wouldn't get run over by a fast moving boat in the middle of the night. I would also probably have to overcome the possibility of motion sickness. I would think though carrying one of these on a bike tour would take up so much room and weight, it wouldn't be practical.
