Viral Video Watch: DC Shoes. Ken Block. Gymkhana Five. Say No More

Following on the viral success of Gymkhana Four, DC Shoes co-founder and professional rally driver Ken Block is back with "Gymkhana Five: Ultimate Urban Playground." Filmed over four days on the streets of San Francisco, it's the most jaw-dropping Gymkhana production yet. The Monster World Rally legend treats SF as his personal playground, with special appearances by rider Travis Pastrana (a DC brand ambassador) and Jake Phelps (of Thrasher magazine). The drifting scenes alone are a thing of beauty — no wonder it generated 4.5 million views within 24 hours of being uploaded on YouTube on Monday. Watch it below.
