I'd be interested, though my knowledge of Depression-era America might be a bit stereotypical (I derive it from The Great Gatsby, Bonnie and Clyde and Of Mice and Men). 

I just wanted to ask, you say that the zombies will ignore would not immediately fatal "like decapitation of destruction of the brain". Was that a typo - or are the the sort of COD-zombies that just keep coming until you completely destroy the body? Can they run?
