Mountain biking in winter

If you live in an area with four seasons, it's wonderful to watch the year go by on a mountain bike. You see each cycle unfold and blend into the next. When the leaves turn to gold and skis and snowboards come out of the closet around the country, my mind turns to ... riding my bike at night in subfreezing temperatures, on bulletproof ice. Winter, especially, offers exhilarating riding-if you prepare properly. When snow and silence blanket everything, the terrain becomes incredibly beautiful.
