From 9:30 p.m. to midnight every Tuesday and Thursday, you can find a throng of skaters grooving to soul, funk, R&B, and gospel. As men breakdance backwards, ladies drop their booties to the beat, and groups of three lock arms to spin each other around like human tilt-a-whirls. The Rollerdrome is the apex of the adult roller scene, so if you're feeling slightly intimidated, know that this crowd is full of friendly, experienced rollers who'll be happy to give you pointers. And always remember the cardinal rules of soul skating: You gotta know how to fall with style, and you've gotta -- gotta
-- have rhythm.
