Yes, this is the sport you couldn’t make sense of during the Winter Olympics. Curling combines the finesse of golf with the strategy of chess, and involves two teams alternately sliding 16 granite rocks down a sheet of ice toward a target. While one teammate slides, two others vigorously sweep (with brooms) the ice ahead, melting it slightly and lubricating a path to victory. The team with the most stones closest to the target wins. Consider this a winter alternative to bowling, and join curlers of all ages at a San Francisco Bay Area Curling Club, which offers “try curling clinics” and lessons at Fremont, San Jose and Oakland ice arenas. $15,
