Zombie picnic in Hyde park

Me and a friend are organising a zombie picnic in Hyde Parl. The idea is that we get as many people as humanly possible to dress up as the living dead (a phrase that still confuses me) and meet in Hyde park (In London, England. Check Google) to eat food and scare the normals. You can put as much or as little effort in as you like and stay for however long.

It's obviously an open event so invite as many people as you can : P
