From Breckenridge Ski Resort via YouTube:

Spring Fever is here in Breck. Today snowboarders from across the country came out to compete in the Mountain Dew Throwback Throwdown where nothing bigger than a 540 is allowed. It is all about style and tweaked grabs in the big pipe as well as the 6 foot mini-pipe. Free concerts among other events and competitions will be happening right here in Breckenridge for the remainder of the season.
