Attending a silent disco should be on everyone's summer bucket list, and today — National Dance Day — is your 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: Boy Bands vs. Hair Bands. Admission is free, but you'll need to have an ID to receive a pair of headphones. The disco takes place from 9 to midnight on U.S. Bank Plaza. (Niesel)
