Dirtbag

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 bad-ass motorcycle, then go and build yourself a bad-ass motorcycle. The event is popular for its burgers, broads, beer, and burnouts.
