Interesting question..... While neither tuna or peanuts will disappear, it's the supply chain that is in question. There could be full warehouses of tuna on the West Coast and full warehouses of peanuts in the Southeast. When the commodities can not get to the market place, they disappear. We are seeing that now, to some degree. The same can be said for prescription drugs, petroleum products, electricity, natural gas and even potable water. The key to Surviving is to be resourceful enough to adapt to the rapidly changing situations. Start looking at your associates from the perspective of "Who has a Survivor's Personality" and not who has the most ammo.
