To the tops of mountains, over water, sand and grass, and of course on snow and ice, snowmobile racers have traversed the toughest terrain to push their sleds to maximum speeds. Competing since the second sled was built, vintage cross country, drag, and ice oval racing have paved the way for today's extreme competition racing at events such as the X-Games Snocross. This book traces the development of how snowmobile racing got to where it is today with influence from sanctioning bodies and organizations like the USSA, ISR, and WPSA and milestone moments in sled-racing history.
