If you see a bunch of people dressed up in '70s clothes and hitting each other with bouncy rubber balls, don't worry. They're doing it on purpose.
Today, Aug. 6, from 6-8pm, head on over to Kesey Square for a few hours of people in bell bottoms and disco outfits diving, dipping and dodging. It's dodgeball disco-style.
It's too late to sign up for the tournament, but it's free to watch, and everyone's invited to play foursquare or hang out in the beer garden.
And if you unwittingly happen to be passing through the area — good luck avoiding stray dodgeballs!
