There are several issues that PETA pursues that I agree with, but this one is ridiculous. The only questionable thing I saw was one horse standing in a regular tie stall (not a box stall) and he looked a little dirty. If these horses were truly being abused, the whole industry would have come to a halt a long time ago.
I agree that most of these horses are probably treated a lot better than some of the backyard horses here in Texas. If people want to concentrate on animal abuse, they need to look beyond the bored carriage horse standing in front of their office building. There are horses in this country that have much worse jobs or no care at all.
