More and more families and individuals are being drawn toward a lifestyle that is greener, cleaner, and more aware. We want to know where our food is coming from, even be able to touch the dirt that it springs from, if possible. We want our children (or nieces or nephews or godchildren) to understand that eggs come from chickens--not just from cardboard cartons on supermarket shelves. We love the idea of building things with our own hands, of picking our own berries, of making fresh bread and spreading it with homemade butter. We are, in short, longing for self-sufficiency.
