THOROUGHBRED RACING: Racing horse Eight Belles is held down after the 134th Kentucky Derby at Churchill Downs in Louisville, Ky., in May 2008. Eight Belles finished second in the race, but two broken ankles forced her to collapse, and the horse needed to be euthanized immediately. The dangers of horse racing have prompted some to claim that racing is cruel to the animals. The AP found that such injuries occur regularly in every racing state. Tracks in California and New York, which rank first and sixth in thoroughbred races, combine to average more than one thoroughbred death for every day of the year.
