Books that helped me get a better grasp of the areas we visited:
White Trash. The 400-Year Untold History of Class in America, by Nancy Isenberg
Colored People, by Henry Louis Gates, Jr.
Deer Hunting With Jesus: Dispatches From America's Class War, by Joe Bageant
At Home in the Heart of Appalachia, by John O'Brien
We flew in and out of Pittsburgh, Pennsylvania, and traveled through Western Maryland and West Virgina.
