In the past few years, women's flat track roller derby has become a sensation across the states. The action-packed sport draws crowds to sit mesmerized at fast-moving skaters who are prepared to bust a move (or hard hit) for a rush of increased speed and a spin of glory around the rink. That being said, I'm happy to announce that the Q.C. now has a new roller derby organization (not affiliated with the Charlotte Roller Girls) called Race City Roller Derby. Its first team, the Charlotte Speed Demons — said to wear sports-style uniforms and use their real names during games — will have its debut bout against the Greensboro-based Gate City Roller Girls on Dec. 4 at First Ward Recreation Center. $10 in advance; $14 at the door. 4 p.m. First Ward Recreation Center, 610 E. 7th St. For more information, visit www.charlottespeeddemons.com.
