MADISON, Wis. -- Channel 3000 is putting out a call to all the vampires, ghosts and ghouls who plan to roam the streets of Madison this Halloween. We need your tweets!

This year's Freakfest, set to begin at 7 p.m. on Saturday, boasts an impressive list of performers as well as the usual cast of thousands of costume revelers marching to and fro along the city's main drag. We want to know what you're seeing and thinking all night long. (Oh, and by the way, we'll take tweets from both real Twitterers and as well as those just dressed up as Twitter-tarians.)

Channel 3000 will be livestreaming the whole festivities from an undisclosed location and liveblogging what's happening. Your tweets will be incorporated into the minute-by-minute coverage.

So how do you do it? Follow us at the Freakfest Twitter page or C3K's Twitter page.
