If you aren't familiar with this phenomenon, a zombie walk is when a large group of people walk down a street as a mob of Romero-esque zombies. They wear zombie make-up, tattered clothes, etc. Good times. This was in honor of the 40th anniversary of Night of the Living Dead.
I participate in the San Diego zombie walk - it happens every year during Comic Con. Last year we had many hundreds of zombies and thousands of onlookers. Lots of fun.
The zombie walk route is near my home, they get on my nerves because the they always cross the street at the end of my block, an entire parade of them and pay no attention to the traffic lights so I'm stuck waiting forever to go anywhere, damn jaywalking zombies. Since I can't beat them maybe I'll join them.
