Competing horses can be any breed and do not have to be registered if owners can prove the horses’ ages. The event will feature vendors and a silent auction with concert tickets, art, furniture and more. Fiely said this is the largest show that the association puts on, and people can also see some of the top reining horse trainers in the world compete Aug. 22 in the Celebrity Spectacular. This will mark the first time these trainers will have competed on cow reining horses, Fiely said. Fiely said organizers hope people will visit the show even if they’ve never seen cow reining horses. "It’s really high energy. You just never know what’s going to happen,” she said.
