@chai2,
I am very glad you are prepared for this.
Do you have a stash of salted poles on the ready?
Either that or I'm going to hide out with David - I know he has a stash of weapontry that would take down an entire zombie apocalist (however you spell it) and I'd imagine he has practiced enough with his guns and rifles and such that he would be able to hit all in the brain. For safety I would help him out and salt the bullets so either way we are covered.
