9/26: Critical Mass, a phenomenon that began in San Francisco in the early 90s, celebrated its 11th birthday on 9/26. The ride, which is paralelled by bicyclists in nearly 300 cities worldwide every month, is mostly an "unorganized coincidence" of pollution-free, space-friendly, fun-loving traffic. Riders were asked to bring their bike, silly hats, noise/music makers, absurd/wicked cool bicycles, grandparents, children, good cheer. Details
