Adults’ skate night falls on every Tuesday at SkateWorld Roller Rink. Bump, shuffle, and roll to the DJ’s favorite skate jams from 7:30-10:30 p.m.; $12 gets you in the door and strapped into a pair of rented skates; it’s $8 if you have your own wheels. Tuesdays are reserved for the 16-plus crowd. That’s when the more skilled skaters come out to demonstrate acrobatic techniques. Everyone’s style has a place, from armored derby girls, to the sharply dressed old-schoolers laying down their moves, to vintage Michael Jackson wannabes.
