There was a Zombie Walk up in Seattle on Oct the 29th. I wanted to go, but was off shooting my new rifle.
Anyway, I found the website with all the pictures, and saddly, it seems that the emo crowd of Seattle's U Village (University) just isn't as ethusastic as people from your side of the Country. My friend Mary went, she said they all went to a theater that was playing Romero's orginal Dawn of the Dead that day just for the Zombie Walk.
here is the link that I found.
Edit: Seems lots of the pictures are from other places in the states also.
