I read Evasion first as a photocopied zine. It was mailed to me in a reused envelope and held together with industrial staples. The pagination was all wrong. Sentences frequently ran off the edge of the page or were lost in the margin.
As a zine, I loved it. Holding it felt like reading a strange missive from a far-off place. As an atypical punk travelogue, it's among the best. In book form, however, it lost some of that tangible mystique and read more like a painfully didactic instruction manual. This transition brought out the reek of unacknowledged privilege and cringe-worthy moralizing referenced in several earlier reviews.
Finally, to echo yet another reviewer, I strongly recommend Off The Map - an empowering, insightful travel-zine-turned-book in the same tradition as Evasion but without the posturing. Off The Map is still in print here: http://www.crimethinc.com/books/otm.html
...and ain't nothing wrong with dumpster diving.
