According to this article, http://www.timesonline.co.uk/tol/news/uk/article4327263.ece, three-legged races and sack races have been banned at an elementary school in Washington because kids just might fall over and hurt themselves. The kids will be allowed to hop and run, however, because the likelihood of injury doing that is apparently less.
Do you think banning these races, which have been done by kids since pioneer days, is a little extreme?
