I live in a northern climate and know damn well that 99 percent of the people here would not make it through the first winter. Most heat with propane or natural gas. A few heat with wood but most of them have outdoor boilers that require electricity. It would be extremely hard to live off the land here considering all the people around and limited game and fish. Food, livestock, firewood and stoves will be in high demand here. Saws and axes would come in handy too. I would not trade any of that stuff for silver or gold.
