Ready, set, roll: Lace up—and dust off—your skates for this inaugural roller disco party. Friday nights are a blast from the past with beats by DJ PopAlot, a light-and-sound show, and a whole lot of skating. Favorite tunes like “YMCA” and “Ghostbusters” are sure to revive the nostalgic feelings. Feeling shaky? Free skate lessons will be offered prior to the event. (Roll will be held every third Friday.) Fri 9 p.m.
