Southside Revolution Coed Junior Roller Derby skaters (and parents) are out volunteering on this MLK Day: They’re cleaning up at Roxhill Park/Skatepark (where we photographed the trio above) and then heading to the South Park Skatepark to do the same. They were planning to do some skating at both parks, too, before practice tonight at their home base, Southgate Roller Rink (9646 17th SW). That’s also where you can see their second bout of Southside Revolution’s second season, in less than two weeks – 5:45 pm Saturday, January 30th; it’s a Harry Potter-themed bout against Spokane’s Cherry Bomb Brawlers. The evening will include a 50/50 raffle and bake sale to benefit Brawlers coach Ti “Smartass” Marchand in her own “brawl” against cancer. More info here!
