From the organizers:
FUNDRAISER THIS WEDS. at the Wonderland Ballroom (11th and Kenyon), starts around 9pm, but get there early so you can buy a CH Day T-Shirt for $20 (or rather, donate $20, get a free T-Shirt). We'll have a band and then DJs (Flexx Matthews and Gavin Holland). Bring your loose change and friends!!
Plus their new website is up, check it out ColumbiaHeightsday.org
