I would say either Fog or Post-Fog. While Post-Fog would be closer to the movie I mentioned, the Mist, I do feel that setting in during the Fog stage would allow for some build up before everything goes to hell.

Also I posted a character sheet in the OOC thread. I'm not sure if you saw it but I made a sheriff's deputy character. Just wondering if they are acceptable.
