The horse who won the Kentucky Derby two weeks ago - he broke his leg in the Preakness yesterday.
It was absolutely painful to watch. This won't make you feel better, but they usually put horses like that down. There's a chance they might keep him pastured to see how he sires, but they don't usually do that. Flat racing is an ugly business.
Barbaro is a Derby Winner, and hence is worth a lot of $$$ as a stud, so they will actually pay to try and save him. Sad, but true, it is an ugly business.
The g.c. is very, very into horse racing. He almost cried, too, and not because of money. It's a cruel business, though, so I stopped participating in it.
