One interesting tidbit of CoG in the US was the plan by the Federal Reserve and the Treasury to replenish the nation's currency supply, most of which would likely have been destroyed or irradiated in an attack. They built a specialized bunker in Virginia inside of Mount Pony loaded with several billion dollars worth of currency, and with it the government would presumably use it to restart a more "traditional" economy in the aftermath of an exchange. The feasibility of such a plan is marginal at best, but it didn't stop them from putting everything together to try.
The bunker itself is still in use today, although now by the Library of Congress to store copies of their entire audio and visual catalog.
