Motorcross To Take Over Oklahoma's BOK Center

Pro indoor dirt-bike racing comes to Tulsa's BOK Center this weekend. Crews spent the day getting the arena ready with 170 truckloads of dirt. That's enough to fill a Boeing 7-47 jumbo jet, or the International Space Station.

Workers used heavy machinery to shape the dirt into a track, and every track is unique. Some of the jumps will catapult riders nearly 30 feet into the air.
