I would make sure you have a generator.

that might turn out to be a sound beacon for marauders, along with having light in the house, once the power goes out, those that have electricity will be noticed at a distance, kinda like smokers, you know they just lit up 500 ft away, you may not see them but you know they're there.

I don't know, in the city here there are so many apartments stacked up every where, there are going to be hoards of people in a very small area trying to survive until respondents arrive, now up in Alaska they're kinda self sufficient anyway due to the climate and they're not all packed in like they are down here in the lower 48, like has been mentioned in the aftermath of Katrina, most of them weren't neighborly at all.

I'm stayin' gray.
