I live in the country, we have a diesel generator that can power our entire house (can be run on bio-diesel, and unlike petrol diesel does not go off) our entire property is fenced, we live on a freshwater lake full of salmon, have wood stoves, a stockpile of food, a garden, two pellet guns and lots of pheasants and critters around to eat. We also have two diesel pickup trucks. For weapons we've got 4 axes (one is even carbon fiber ;o) and lots of tools to make other weapons even. We do have a gun although its from the 1800s.. I guess we could put blanks in it just too scare people.
Sooo yea if something like that were to happen I feel like me and my family would be pretty well off..
