Yeah how is the Slip & Slid not on this list? I remember that as a kid we had one with a ramp and "splash pool" at the end of it, except we always set it up going downhill with the objective to ramp the splash pool. Also the company that produced those "pegs" for bikes so people can stand on the axis of your front wheel and on the back. Full speed down a hill with 3 people on 1 mountain bike, middle of the road, no helmets. The only way to do it.
