> Some people have been completely isolated in their homes for 8 days. I'd say most people, even in rural areas, don't have a supply that'll last longer than that, except for some hardcore preppers.

I wouldn't say that, I try and always have 3 months supply of food on hand in case something happens, even just a temporary job loss, in fact the idea of having less than a full months supply of food on hand seems terrifying to me, as evidenced all you need is one bad winter storm and your looking at starvation.

In fact the church I belong to encourages members to have 1-6 months supply of food on hand in case of emergencies and it would be something I'd recommend everyone do. It gives you substantial peace of mind.
