Any survival guide will tell you, don't buy a pair of combat boots before any disaster. They'll tear your feet up. Or water - don't bring water with you because it'll tire you out and you'll lose too much fluid. Bring a water pump.

I doubt very much that the chief executives of any of the Fortune 500 corporations can name five edible plants, five native grasses, or five migratory birds within walking distance of their homes, or name the soil series upon which their house sits. And I would contend that if you don't know where you are, you are in fact nowhere at all.
