Bring Your Own Big Wheel is a free Big Wheel race where big people ride kid's toys down Lombard, the crookedest street in San Francisco. The funniest thing about this was the amount of tricycle parts sliding down the hill. You can see several wheels rolling down the road by themselves, but that didn't seem to stop anyone. People continued sliding downhill without them. At 2:08 a guy climbs back on his broken trike, re-installs the handlebars, and gives them the finger before taking off again. I took some photos too.
