Alright. This sounds like fun.
We're trying to create a self perpetuating Zombie Mob in the streets of
San Francisco on Saturday (Saturday, July 30th). A seed group of
zombies will start at St. Mary's square, and as we march up Market St.
we'll attack Willing bystanders, converting them and giving them
ingredients to make more zombies. We'll end up at Union Square, Eat
tourists, then eventually hop a train to Colma for a Picnic in the
Cemetary. There's a reception afterword at Launchpad with Blood
Wrestling and Zombie Olympics, then Movies and Music. See
eatbrains.com to get involved."
