From Bill's blog:
The first segment tonight is about the big US Cross Country Snowmobile Race in Lake Parlin. This part of snowmobiling is growing rapidly. Essentially everybody who has ever been on a sled has prepared for this kind of racing. However, too much speed on the trails does not help the sport. These races are the perfect place for anyone who wants to drive a snowmobile fast.
For more information about the USCC, just check out their website.
