In a large scale, non-localized, panic-inducing threat, bugging out isn't a very viable option in many cases. Specifically those of us living in heavily populated areas.

Consider for example, there are several million people in the Puget Sound (greater Seattle) area. If they all headed for the hills at once, you are not likely to get very far in any reasonable timeframe unless you had early warning or you already live on the outskirts, or have some other angle (boat, plane nearby).

I don't think this is a very easy problem to solve. Certainly if anyone has a bright ideas (other than move) it would be great to hear them.

In my case, I'm certainly inclined to SIP unless really pushed (house underwater type thing). From that perspective, I think just having a BOB with reasponable provisions would be good enough improve your situation.
