There are a number of irresistible ingredients that go into a Bay Area Derby Girls match. The base is a mixture of sheer skating skill and loads of lady aggression. Then that gets dressed in bad-ass outfits and sprinkled with unabashedly punny nicknames (e.g. Abominatrix, Imelda Snarkos, and Kristi Yamagotcha). This weekend, there is a double header cooking up at Craneway Pavilion for the last match of the season. First, San Francisco ShEvil Dead will go against Berkeley Resistance for the third place honor. Then, BAD’s winningest home team, the Richmond Wrecking Belles, will face off against last year’s champions, the Oakland Outlaws, for this year’s title. There will be sweat and spit and spandex. On top of that, the event promises a herd of food trucks, a full bar, plenty of local retailers, and merch, so you can drunkenly buy T-shirts while you root for your home team. Remember, this is no Hoodslam performance. This is a legitimate sport that just happens to be more fun than other sports, so be ready for some serious athleticism.
