Anyone can go to the movies or out to dinner, but you won't find someone named Devotchka DeLarge racing round and round a roller track at a theater or a restaurant. Nor will your favorite eatery offer WhoreChata, who is one of Arizona Derby Dames' superstars and not a spicy condiment, or Nikki BadAzz, who inspires crushes in men and women alike as she whips around in ever-faster circles on a suspended roller track. The Derby Dames used to be a flat-track league, but in 2010 they became the only banked-track team in the state, meaning they play on a curved, elevated surface. And, oh, how they play. When they're not competing, they're training young girls in a junior league called Minor Assault, where girls ages 10 to 17 learn how to compete in this most popular contact sport, because (as the Dames say) it gives them life lessons in how to be strong women who can take charge.
