If you woke up in the morning to closed banks and runs on all atms, how long could you survive with our money on hand?

Would you consider having some level of cash stockpile? 

If the SHTF, money will only hold value for a short while. So, I'd rather (and do) keep food supplies and just enough cash to get out of dodge if needed.

My SHTF scenario that I work off of, is hyperinflation. I don't know when it will happen, but it has to. No one can print paper money like the Fed is, at such levels and for so long without consequence.

Up to now, the real estate bust and the banking disaster has tamed fed created inflation by reducing money supply (deflation). But that's coming to an end.

The hyperinflation will start (perhaps paradoxically) as the economy improves. At least cheap natural gas will reign some of the inflation down (low energy costs = lower costs of goods = less inflation). But still, only way to reduce the real value of the debt, is to hyper inflate, and the Fed will create it if it doesn't come about on it's own.
