I hope we're talking about those slow, stiff and mentally disabled types of zombies. If they have any ability to actually think, I'll consider myself (un)dead. But I'm not going down without a fight - I'm gonna have some fun with those things. Well, as much fun as a flamethrower, blunt/ sharp objects and discarded vehicles of the converted allow.
Well actually, that's more of a last resort than what I would do. I'd probably just hide somewhere. Only move by night, only move alone. Hmm... zombies can't swim can they? Because a boat would be one way. Live out on an island until winter passes and see if they all froze to death. Then pillage what I can and-...uh...hmm. Not sure where I'd go from there.
Tell the truth maybe it would be easier to just get down with the sickness.
