Video: Wild Ride down immense dirt hills (on snowboards and bikes)

Where can you snowboard and ride your DH bike at the same time? A rock quarry, of course! Athletes Brett Tippie, Jake Tippie, and Graham Agassiz drop into the dirt in this video on bikes and boards, racing, riding, hucking drops, and crashing more than once on the fast, dirty descent. —Stephen Regenold
