Krakauer, who previously wrote an article on McCandless for Outdoor Magazine, painstakingly traces the young man's years on the road as he went through various jobs and adventures. Hearing of McCandless's lack of preparation as he travelled through various deserts and into the Alaskan wilderness, many readers regard the young greenhorn as a naive dare-devil. Having done some lesser versions of McCandless's vision quest in my 20s, I can personally understand the psychology that moved him (And does anyone in their 20s prepare for anything?), particularly the call of the solitary life in nature and the challenge of living off the land.
Since the book reads something like a detective story, I won't spoil the plot by giving the conclusion--suffice it to say that McCandless actually did a pretty good job of living off the land but eventually died--probably due to a few very minor errors. I suppose the lesson to all wilderness lovers and hermit wannabes is that there isn't a great margin for error when your out in the woods alone. I like Krakauer's book. It's nice to read something for once about a person who isn't on the treadmill of success--a unique individual who's able to decide how to live their own life without reference to TV advertisements.
While I'm at it, I'd like to put a plug in for Book Crossing. Although I've never tried it, the site allows people to intentionally "forget" books on park benches so that others can pick them up. It sounds like my sort of thing--a market economy minus bosses and the exchange of money.
