This one's on a child suspended for doing cartwheels because they are "dangerous." (But they allow other sports to go on at school.) My kids did gymnastics for years, and they didn't get any more injuries than they did playing basketball. In fact, when I was in school, they taught those things in gym class and we were supposed to practice at recess. Illegal cartwheels? I'll bet if cartwheels were on the standardized tests, they'd allow them and forget all about the danger theory!
