build a wood gasifier so that you don't have to rely on gasoline.. (as long as you can get firewood!)
you can use this to power any number of generators...
heck, you can even build wood a gasifier for the tractor
i'm not knocking the koolaid drinkers.. i've been known to drink a cup or two of "bug juice"
but seriously..we've seen some huge natural disasters, society recovers and rolls on.. everyone should "be prepared" as an individual, but society should be prepared as well.. i haven't completely lost faith in humanity!
