looks like a fun way to hurt yourself
Mad River Rocket Sleds
Ditch the traditional saucer sled and have a ball this winter on Mad River Rocket Sleds ($95-$275). With two adult styles and two for children, the company's sleds offer quick-release lap belts and comfortable knee pads that allow you to ride in the kneeling position, improving control, balance, and steering capabilities. Just remember to watch out for trees.
