Watch Bombuj. An amusing view of the machine that has taken the country by winter storm: the snowmobile, revving, raring, ready to go. What the motorboat was to the summer lake, this motorized sled now is to the snow-covered fields. This film shows it all--the pull of this sit-down sport, the eagerness of the trade to keep it booming, the daring rivalry of the racing crowd, and the bemused pleasure of the family outing.
