Have you been through the Mid-Atlantic? It's a beautiful part of the country, rich with history and views, and the most diverse region of the country in many ways! This list works out to an average of 40 cities per each of the 7 states. If you make it to all these towns, consider yourself the GOAT Mid-Atlantic traveler!
EDIT: I know, I know, I didn't include Lancaster and Williamsport, PA. While this isn't supposed to be an exhaustive or comprehensive list, leaving off those two fantastic places was a forehead smacker when I realized it.
