Interesting: 9 years without spending money

Daniel Suelo wasn't poor, a victim of bad luck, mentally ill, or even uneducated. He just decided that he wanted to have nothing to do with money. So he gave up consumer culture altogether, and for the last 9 years, he's survived by living in a cave in Utah, and dumpster diving, foraging, fishing, and occasionally hunting for food. He spends his time in the great outdoors--and in the public library, where he blogs about it all.
Suelo must have the lowest carbon footprint of any blogger in the United States. And he's never taken food stamps or other government assistance, and despite what his lifestyle may lead you to believe, he's certainly not crazy. He's just got an aversion to money.
