Found this irrefutable evidence
I'd like to say a big thanks to everyone who made last night's 1st Adelaide Zombie Walk a night to remember.
Despite a few small hiccups, such as the walk starting 45 minutes early due to its anger at an attempted hijack by a religious nut, and the energy of the undead causing them to lurch through the streets faster than expected (much to the surprise of the after show venue), the 250 strong zombie army (maybe even more) made us proud! Thanks to each and every one of you.
