This weekend I worked on my food stores. I looked over and counted every thing. My food supplies are 80% Mt. House #10 cans and the rest is 5 gallon buckets with dried foods. I moved some of my 5 gallon buckets to put all of them in one place. As of right now for me my wife and the one kid I have at home I'm sure we have a year or more worth of food, and this is not including my food I get from my fishing and our garden. I look at the fish and garden as the extra or my fall-back food. Plus I'm not including any hunting, which I can do and I do well. I'm no expert but I know my way around hunting and there are lots of good things to hunt near me. I do expect as the SHTF for food not just at the stores but the food we hunt to get gone very fast. Most people don't know how to fish or hunt, but the ones that do we be doing it and I would expect that this skill will be very useful in a post SHTF event. As I have said before barter will be the new money and skills and trade items will be how most will make a living.
My friends time is short so get yourself ready and stock up on as much as you can, because food, water and other supplies will be your life line.
