edition. By Phil Boas: “IF SWIMMING POOLS WERE TIGERS, WE’D ALL UNDERSTAND. My father, who was a Phoenix pediatrician and later pediatric radiologist at St. Joseph’s Hospital, saw way too many child drownings and the terrible aftermath of near drownings. He used to say people in Phoenix have a tiger in their backyard and don’t even know it. In fact, he said, we might be better off with tigers than swimming pools. At least then parents would always be alert to the threat. As we enter swimming season, fear the tiger in the backyard.”
