This isn't about seeking maximum efficiency or always defaulting to low price or any other of the concepts which most regard as natural economic laws. This is about doing something productive for yourself, something which produces tangible value for you and your family, and which allows you to practice a skill which has nothing but upside should the world experience oil price shocks, transportation interruptions, labor unrest, or rolling bankruptcies - any of which might make good food hard to get.
Remember, food is freedom. If you are looking for high-quality old school gardening and truck farm tools, I highly recommend you check out Easy Digging and then get to planning that garden.
