Interesting, because I would like to make the trip and because I've been to many of the places the author visits. But he's disappointingly brief in many of his descriptions and skips other places entirely.

He's also a liberal. He seeks out other liberals and gives them their full say while adding his own comments. He doesn't talk with many conservatives, or give them a chance to support their views and he usually paints them as silly or ignorant (which some of them are).
