The Line King: The Al Hirschfeld Story

What can you build with a grand and a month? The Dirtbag Challenge is an event that takes place every year in San Francisco. It''s a grass roots, low budget chopper build-off and party, and besides being a contest, it''s also a concept: if you want a killer motorcycle, then go and build yourself a killer motorcycle. The event is popular for its burgers, babes, beer, and burnouts.
