It's doomsday plus a few weeks. Say you need to bribe the border guards at the state line but they seem to have all the wristwatches and free range eggs they can use. Hah! There's nothing like a few good ol' silver coins to become their number one tourist, let this man through. Or your gas station's not accepting Visa and the ATMs have gone dark from sea to shining sea and you've got a hard to get reservation at a fallout-free retreat. Hah! Dazzle 'em with the sheen of silver my friend, fill 'er up and happy motoring to you.
