As my grandfather used to say, "Always have a back-up plan." Not only have various currencies, tangible and intangible, but get to know your neighbors in your communities. Self reliance is great up to a point. Once the SHTF, we really will need to work together to feed each other. We might as well start community gardens and the like now instead of waiting until it is absolutely necessary.
