It is pretty much a copy of the era surrounding the 1929 Stock Market crash, only much, much bigger, this time !! Store plenty of rice and curry powder, in a dry place. You can have anything curried with boiled or fried rice. Rabbit, hedgehog and squirrel, are all edible, as are deer for venison. Pigeon pie with a dash of curry powder is pretty good too.
Always carry a very sharp boning knife in your car and if you come across a dead cow, in your travels, cut out, from the middle of the top of the back bone all that you can. This is where the steaks are from!!!! Cracking the main back bone, at each section, gives you T bones or cut them further into sirloin and fillet steaks when you get home.
Should things get really bad, the barter system will return. So I would not be having any Spring cleaning or garage sales this year. That old bike could quite easily be turned into an electrical generator!!
