You'd have thought they'd have found a way to CG the horses or rewrite it somehow. I think they were caving in to PETA. Something sure wasn't right if that many horses kept getting hurt.
OMG! I just watched the last episode! It was getting so good...I wish some other network would pick it up and use OLD RACE footage or CGI like you said Wes R! What a bunch of dumb@sses for NOT going that route! :facepalm
