Due to deaths of horses in accidents at the track.

I have been to horse races where horses had to be euthanized, and for ME, it was a tramatic thing to watch. I no longer go to horse races because of it. I now (me personally) see it as exploitation of animals and I love animals. (I love animals that make a good gravey as well )
