Survivalist Mentality
Americans have been prepared for anything in the past, so cosmicfoole is living up to his name. The ones who were prepared were primarily early pioneers who brought what they needed and made everythign else while living off the land.
I'd be happy if all americans stockpiled 1 months worth of supplies: food, water, fuel, hygiene, first aid+, clothing, repair materials. By the way, hygiene and food supplies should be rotated out and replaced before they become outdated. I find that stockpiling $500 worth and donating that yearly to the local food bank keeps my supplies fresh, helps those who need the help, and (if you keep your receipts) takes care of that tax deduction for charity at the end of the year.
3 months supplies is better. If you're going to survive a world-wide catastrophic event, you need at least a year's worth, plus viable seeds, farming and building supplies.
Some disasters require migration: coastal subsidence, super tsunami, invasions, volcanic eruptions, etc. Unfortunately, migration and long-term survival supplies don't go well together.
