Dave Downing was a pro rider for Burton Snowboards in the early and mid nineties. Check out his part in Mack Dawg's The Stomping Grounds and you'll see why he was one of the most well rounded pros of that time. It contains Japan pow shredding, park, pipe, and back country cliff shots and even some surfing.
Dave's early ambition to become a pro surfer lead him to become an influential professional snowboarder. He still works for Burton and has been described to me as Jake's right hand man. and he's married to Shannon Downing (formerly Dunn) who was just inducted into the snowboarding hall of fame.
