hmmmm. 60 Minutes just had a pretty reasonable piece on Preppers. Talked with the guy who runs 'ThePrepared.com'. Seemed to me to be encouraging folks to prepare. I've also been seeing an online article telling folks they should be putting back ~$2,000 in case of a 'national emergency'. This is a Yahoo article that's been popping up off and on for a few weeks for me. Is this the sheeple being warned?
Cash is going to be useless unless you have enough to burn and cook and keep warm with it in a long-term grid down situation.
Nobody with half a brain is going to trade hard goods for cash. In an emergency situation (especially long term), trading in material goods will rule the day.
Food, water, shelter, lifesaving drugs, alcohol, guns, ammo/security, seeds, petroleum, tools, communication equipment (radios) with solar charging capability, clothing, blankets, medical supplies (not a pocket boo boo kit), will ALL take precedent over cash in any exchange.
