Bay seniors with only a fuzzy knowledge of Genghis Khan might want to learn more about his ancient and nomadic culture by joining the Mongol hordes descending on Golden Gate Park this Saturday for Naadam. It’s a festival that includes traditional archery, wrestling, tug of war, costumes, food and crafts and takes place in Hellman Hollow from 12-5. Adults $8. Kids free. Unfortunately no horse racing, a major activity of these equine tribes. Instead kids run with toy horses.
