Anyway What did they do, put a piece of plywood on the bottom of the couch? I was thinking of "sledding" behind the boat in one of those heavy duty utility/ice fishing sleds that are shaped like a jon boat. I would think it would work, but be a bit dangerous.
"Couching" looks like fun. Also heard of people dragging people on a mattress behind a truck during winter, and riding on a lawn chair strapped to a sheet of plywood behind a boat
