I was in Newnan, Georgia, a couple of weeks ago. The Walking Dead is being filmed in the surrounding area, the local high-school's sports courts had just been used as a FEMA refugee camp which had been over-run by zombies. We went to the little town of Senoia, zombie central, but alas saw no shambling brain-eaters.
Would have been amazing to see some :-)
Came back to england... Leeds on a saturday night is full of them.
