CDC preparations for Zombie Apocalypse

The US based Center for Disease Control has a rather amusing zombie preparation plan on-line which I had heard about, but only recently found. It was initally done as a tongue in cheek way to get people to take emergency preparation seriously, and has become something of a cult hit on the web. I'm not sure how real they think the threat of a zombie apocalypse is, but it never hurts to be prepared, as the following photo from the annual zombie walk through Brighton shows!
