Rocket Sled
Love sledding but hate having to drag yourself and your sled back up the hill? Try Acme's Rocket Sled. You'll be up and down that hill 15 times by the time your friends have trudged uphill once. The Rocket Sled requires jet fuel to run, and has a 2oz gas tank in order to keep the sled as light as possible. You'll want to keep a supply with your nearby as you get 5 minutes of runtime off of one tank of gas.
