These people in San Francisco probably had more fun than you on Passover/Easter weekend. BB reader Bhautik Joshi shares his photographs from "Bring Your Own Big Wheel 2012" in the Boing Boing Flickr Pool, and explains the idea behind it—

For the uninitiated, the gag is really simple: – large group of adults in costumes assemble with a variety of wheeled, childrens toys (Group A)



– large group of spectators gather (Group B)



– Group A races down windy Vermont St as fast as they can, leaving a trail of noise and awesomeness in their path



– Group B cheer like maniacs

What's the story behind this fellow's costume, I wonder? Perhaps one of you can fill us in, in the comments. View the full photo set here. Here's Joshi's website.
