"...If it's nationwide, think about where you want to be long term..."

Just remember that fuel will be hard, if not impossible, to get, so if you plan on going somewhere you will undoubtedly be fighting for road space and fuel with a jillion other people. Think of the gas lines of the early '70's a thousand times worse. Throw in the panic factor, and things on the road could/will get very ugly...
