In the summer of 2000, Middlebury author David Haward Bain took his family on an eight-week, 7,000 mile road trip across the United States. The trip is recounted in Bain’s newest book, “The Old Iron Road: An Epic of Rails, Roads and the Urge to Go West.” In the book, Bain takes the reader through the ghost towns, battlegrounds, museums, and train yards that tell the story of 19th century America.
