A racetrack in Auburn, Washington has come up with a unique way of filling the stands on race day: by going old school. Like really, really old school.

Over the weekend, Emerald Downs racetrack hosted its third annual T-Rex Race — as in Tyrannosaurus Rex. Instead of using Jurassic Park technology to bring the prehistoric beasts to life, Emerald Downs uses people in goofy-looking dinosaur costumes. But fans don’t seem to mind. “The crowd response is the best part of the event,” says organizer Cody Bennett. “The kids love us, and we enjoy taking pictures with them before and after the race. It’s always enjoyable to hear the adults making bets with each other on which T-Rex will win.”

On Saturday, those who bet on Regular went home happy. He beat Rex Girlfriend by a tail to win the race.
