Well, as a good Mormon, I already have a year's food supply for my family already stored in my house. (About 3 months of which is the food we are accustomed to eating minus perishables). That will be enough time to slowly acclimate our systems to eating more grains and long term storage. I also have 150 gallons of water stored in my garage. Once that's gone or if I need to leave temporarily I have water filters that will do for a short amount of time. By then hopefully rainwater can replace what is lost or perhaps I can refill at the river if I have gas left in my truck.

If there is a need to evacute, the home storage won't do us much good, but it may be possible to come back to it. I don't live in a floodplain or an earthquake or coastal zone, so there is a good chance the house will survive. We have 72 hour packs ready to go which will keep us from getting hungry for those critical first few days.

I don't have a generator, nor do I have extra fuel, so those I would need to scavenge. My father-in-law has a kerosene heater with a 50 gallon barrel of Kerosene in his garage. Since he lives in the same town, I could easily go get it with the gas in my pickup.

As a mormon, I know other mormons who have what I don't. If they survive it wouldn't take long for us to inventory what we have and form a protective community. One thing I know I am lacking is weapons. Depending on the circumstance this may or may not be an issue. If there is no other survivors, I know where I could find enough. If there are, than I would band with those I know who do, and scavenge what I could for myself.

Growing food isn't such a problem in my climate. I have about 100 s.f. of grow boxes in my backyard which can grow quite a lot as it is. I could easily expand those and have a large enough garden to feed my family and store up food for the winter. Meat is a little tougher to come by, as I'm no hunter, but I could probably barter for some.

I think those who are prepared and intuitive enough don't need to roll over and die. There are certainly other options available. It won't be comfortable, and right now I'm thinking maybe I need to add a few large bottles of Tylenol to my supply, but we could adapt. The first generation will have it the toughest while we relearn the skills we've lost, but the 2nd generation would build off of that and by then will have some sort of infrastructure running again or will have at least adapted to the land. Meanwhile those living in major cities won't have much of a chance I'm afraid and will be either dead or gone within 3 weeks. Leaving will be tough if they don't have relations out of the cities since the locals won't be very keen to support the hordes trying to evacuate when their own future is so bleak.
