AQHA Judges Bill Enk and Todd Williamson dissect the winning cutting run of Mattie Dukes and One Time Player at the 2016 Built Ford Tough AQHYA World Championship Show.
Yellowstone is a really great show, I love it too. But this event in rodeo is called "Cutting". The term "Cutting" refers to the act of separating one cow from a herd of cattle. The rider is judged on how well she and her horse can keep the cow separated. It does look like fun. I'd love to learn to do it too.
