And if things got truly out of whack, wouldn't it be more likely people would head for super wal-mart and other big box/grocery stores rather than homes?
And when you get there to find them fully occupied or empty of goodies by the other millions of you?
And when the resources of the local and regional Red Cross, churches, etcetera, are gone, I ask again are you assuming the government can and will adequately respond?
We can continue this infinite regression [you post a what if and I counterpost a what if not], but I guess it comes down to this: do you prepare for the potential for evacuees and refugees overwhelming local resources as if it was in itself a disaster or emergency, or do you think your preparations for other disasters and emergencies covers the situation.
I propose that you think through the first possibility. If you have done so and decide that scenario is too unlikely or that you are already prepared for it with no changes, fine.
Dweste, you haven't defined the scenario well enough to venture a reasoned assumption on the government's capacity to respond or in what time-frame it could adequately respond.
What is "it?"
Two million evacuees? Five million? Ten million?
The entire New York metropolitan area?
Washington, D.C.? Denver? Los Angeles?
In winter? Summer? Spring? Fall?
Was the place they evacuate from obliterated so they can't go home again for a decade, or ever?
Did they have a heads-up, such as in a hurricane, so that they could pack their cars with supplies? No warning, ala earthquake or nuke? Dirty nuke and bio-terror that could compel a populace to flee and have the opportunity to do so?
Where, what, when and how many matters, a lot.
I don't believe that Americans (or any other civilized people) fleeing a metropolitan area for any reason will be left to fend for themselves -- abandoned by every level of government, in every state, by every other entity in America (for-profit companies as well as non-profits have helped with other disasters) and the American people.
And I don't expect those people to become a massive mob of marauding savages. If our televisions still function, we're going to be seeing video of people just like us: children, seniors, disabled, women, men. Odds are that some of them will be old friends, colleagues or family.
So, no, I won't flee. I will sit tight and help as I can.
And if our government doesn't help our own people in that situation, there will be heck to pay at the next election.
