Attending a silent disco should be on everyone's summer bucket list, and today is your final chance to check it off. Grab your friends and head down to Playhouse Square this evening to dance about in silence while wearing wireless headphones. Tonight's theme: Adult Prom. Wear your old prom dress or tux and be prepared to hear the best power ballads and line dances. You can even get a photo with your "date" in front of a special backdrop. The disco takes place from 9 to midnight on U.S. Bank Plaza. It's free. (Niesel)
