Arnaud De Bluze honors Sam Trowbridge with a ride down Lombard St wearing (just) a helmet. Early 2011, we lost one of the best riders on the Freebord team, Sam Trowbridge, 21. He was riding down a routine hill and took a bad fall. He wasn't wearing a helmet that day. A simple skateboard helmet could have saved his life. Ride for Sam.
