A four-year-old boy drowned to death in the 2-foot deep section of the wave pool at Great America in Santa Clara yesterday. There were six lifeguards on duty at the time, but there are no age limits on who can use the pool. Authorities have not identified the boy, or said whether or not he was supervised at the time of the accident. This is the first drowning at Great America but not the first death -- the Chron lists the other four people who've died since the park opened in 1978 (one person hit by a roller coaster, two people fell out of rides, and one person was killed when two roller coaster trains collided.) more ›
