While reading BoingBoing I discovered the BYOBW race that is held each April in San Francisco. 

In case you were wondering, BYOBW stands for Bring Your Own Big Wheel.

The race takes place on that crazy curvey road called Lombard Street. 

One of my favorite toys growing up was a Big Wheel so this means I'm going to HAVE to participate in BYOBW some day.
