Imposter horse was the 'favored' horse

I know the Horse ID staff in NY and they are very thorough. They don't check the tatoo, but they go over each horse, especially the "plain brown" ones. Since the women who do it are "horse people" they are pretty sharp with knowing who's who.

At Tampa they do a tatoo check as they enter the paddock. I think they do the same at Suffolk.
