The world's top hoon has turned the city of San Francisco into his Ultimate Playground for GYM5. Block's team -- headed by director Ben Conrad -- filmed the action over four days.
The epic result features cameos from DC athlete and longtime Ken Block friend, Travis Pastrana, to make a cameo appearance on his dirtbike, and S.F. resident Jake Phelps of Thrasher Magazine.
But the real supporting star is the city itself, with Block showing it off in a way it's tourism board has probably never imagined.
However Block has obviously had some official cooperation from city hall, with the streets being cleared except for a couple of San Francisco's iconic trams -- which he puts to good use in his signature style.
