dweste, since you're asking about passports in a BOB in another thread, I'm just curious, did you have any specific situations in mind when asked about EDC'ing a passport? Because since you live in central California (that's correct, right?), not particularly near the border, I can't really think of any reasonable situations where you'd need a passport instantly, without going home or to your safety deposit box to get it. If you're just thinking of the passport as a form of identification, rather than as a travel document, then I would say that other ID like your state drivers license should be sufficient in any disaster scenario, particularly if you have documents like credit cards, health insurance card, etc. in your name on you, too.
