Query: Couldn't even finish it.

This is one of those books that is written for a European audience, with all the currently trendy, shallow prejudices that are currently marketed by their mass media. It has very little to do with the Appalacian Trail, which he abandons halfway through the book after traversing a small fraction of its length. The author can't even tell the difference between the National Park Service and the Bureau of Land Management. But hey, at least it has wit. Half of it, anyway. The time I spent reading it was utterly wasted, but Europeans ought to enjoy it. For Americans, find something else to read, like Twain's "Innocents Abroad", for example.
