on a roll - View this location on map Roller-skating is an integral part of hip-hop culture in Atlanta, which is home to OutKast, Usher and Young Jeezy among other stars. Beyoncé had her 21st birthday party at the Cascade roller rink here, and Dallas Austin paid homage to the flawless moves of skate dancers in his recent movie ''The ATL.'' On Friday nights, the virtuosos descend on Golden Glide ( it's tucked behind a shopping strip, 404-288-7773; www.atlantarollerskating.com) for adult skate, where posses practice their smooth moves (11:30 p.m. to 2:30 a.m., $7 including skate rental). If you haven't been practicing, skate inside the green line for your own safety. Or just stay on the sideline and gawk. New York Times 2750 wesley chapel road, Decatur, GA Active, Kids
