On July 23rd, around 5:30 PM (PDT), a Comic-Con zombie walk broke out in the Gaslamp District across from the convention center. I hadn't heard about it in advance, so I was lucky to stumble upon it.
Most folks dressed up as ordinary zombies, while some were zombie versions of super heroes or various celebrity zombies. There was one Ash, which was a nice touch.

A few people dressed up in military gear to contain the outbreak. When I told them they were doing a terrible job since there were zombies everywhere, they shot back, "Have you been bit?" How did I not see that one coming?
