"We brought a wild horse, and pretty much a wild girl, and they have both changed just incredibly, both horse and her," Bobby Kerr said.
On competition day, Kelsey didn't make qualify for the main event, but her father did, and 5,000 people packed into the Will Rogers arena to watch the final showdown.
Recreating his favorite scene from the movie, "Tombstone," Bobby Kerr had his horse Trigger jump through a giant waterfall, demonstrating how he had built up enough trust with the horse to keep it from being spooked.
In the end, Kerr didn't win, but still managed to take home $160,000 in prize money. For him, the endless hours of training reaped a different kind of reward -- bringing him closer together with his daughter.
"He's always been my hero," Kelsey said. "I feel like I can relate to him."
"There's nothing better than getting approval from your family," Bobby added. "That's when you feel like a winner. If your kid thinks it's cool, that's really worthwhile."
