I'll be honest, the lineup this year is probably the worst ever, but it should be a fine day outdoors (per the Fox5 forecast). Anybody else going?
For those unaware, it's a yearly event held by a DC radio station. It's not so much a "cookoff" but there will be chili, and live music. Soundgarden is the only one I marginally care about. I've never been a huge fan of them (or alt rock/grunge) but attending a show of theirs is on my bucket list.
