This is a longish read but pretty much covers everything from poor weather to cannibal bunnies. A few lost digits are tossed in for effect. Anyone whom thinks they can run off and live off the land are deluded if they don't take stock of what it actually takes to put your own food, on your own plate. Food storage ideas are great, but the knowledge of when to plant (covered rather funnily in this story) what, how to take a seed from start to freezer, the how's and why's of animal husbandry...all covered...is golden.
