For the uninitiated, the Humboldt Roller Derby is AWESOME. Not just because they kick ass literally, but because they kick ass when it comes to generosity. This Saturday, Humboldt Surfrider is the chosen beer beneficiary. We'll be pouring all evening long! Come out and support your local Surfrider chapter while checking out an amazing sports event – don't wait to get tickets! They tend to sell out and sell out fast! (Bring extra cash so you can pick up a North Jetty Betties T-shirt: $15 each or two for $20.) Full details on the poster below.
