Yeah cities. But briefly. Richmond, Raleigh, Columbia, Atlanta, Mobile, Biloxi, Jackson, New Orleans, Houston, Santa Fe, Phoenix, Carson City, Denver, Cheyenne, Coure de Lane, Spokane, Olympia. Just a taste. You could spend 2 weeks in a single city alone, but the US is not a single city. If you're talking about showing America in all it's colors, shapes, and nuances, then that's the closest you're going to get. Major cities are overwhelming and should be explored as a singular event.
