People dressed up as zombies attend the annual Vancouver Zombie Walk 2011 in Vancouver, Canada, Aug. 20, 2011. The walk started at the Vancouver Art Gallery and ended up at the beach, near the English Bay. Zombies taking part in the event were told not to smear any of their bodily fluids on anything. This year's walk attracted hundreds of zombies and was biggest to date. [Xinhua/Sergei Bachlakov]
