On any given Friday or Saturday night, you can join the cool kids from middle school once again. For $6.25 or less, don the brown and orange skates of yore and cut loose to the sounds of Cheap Trick, Vanilla Ice and J. Lo. You might even catch sight of a staffer or two clinging to the wall for stability and jealously eyeing the preteen speed-skaters. It's a helluva good workout (you'll realize how good when the aches hit the day after), and fret not, the Lucky Number game, the races and the Couple Skate live on here. Lace up and roll out.
