But it's not all blocked onramps and gas stations this weekend! There's also some bus reroutes, courtesy of the delightful YMCA Chinese New Year Run on Sunday at the Chinatown YMCA (855 Sacramento Street). The fun starts at 8am, and registration's $35. According to the website, "random awards will be handed out at the end of the finish line." Random! What fun. A pair of tweezers, some month-old cheese, a hedgehog, forty-two pounds of wigs ... readers, if you participate in the run, please let us know what they wind up giving away.

After the jump: details!
