This book: part humor, part travelogue, narrates Bryson's road trip across the United States and back again. Bryson travels without strict itinerary, and with frequent stops in small towns across the country. The narrative is written in classic Bryson style, with frequent diversions to explain the origin of many of life's oddities, and with constant sideline commentary. As is usually the case with Bryson, the narrative is illuminating, amusing, and shows Bryson's sense of adventure. It was a pleasure to read. Yes, Bryson is frequently critical, but it's important to note that he's an equal-opportunity offender. Wherever he goes he brings his decidedly sarcastic wit, but he also balances criticism with admiration. This is not a book with a weighty message about humanity or morality, but it is a fun read to pick up and put down at leisure. And the ability to dive in and out is one of the beautiful things about this book; one can enjoy it and put it aside at will, and it takes little time to become reengaged in Bryson's prose.
