A unique tradition in San Francisco commenced once again on Easter Sunday as the 11th annual Bring Your Own Big Wheel race was held in Potrero Hill.

Held on a steep portion of Vermont Street between 20th and 22nd, participants were able to race down the steep grade using their very own big wheel, but only after signing a waiver.

The race brought out big wheels big and small, costumes galore and thousands of excited onlookers.  Here are just a few images and videos of the annual event.http://www.youtube.com/watch?v=aYS90IJ1S_I
