Get yourself a flintlock rifle and a cap and ball revolver. Stock up on percussion caps. You can make your own gunpowder and cast your own bullets. You may want to start bottling and saving your own urine now, for future use in powder making and convert a part of your yard to a place where you dispose of your solkd waste. Sure, some people might think you are crazy, but you will be ahead of most of them. Solemn nod.
