I know different people have different definitions, but this is my method of "slow travel". I love taking the state/US highways like this. As long as I'm not in a hurry, I do stay in these little towns overnight, visit sights, and exit through the gift shop. 30 and 22 are the only two I've really done this with in PA, but this spring I plan to visit as much of the northern and half and north-central of the state as I can. I'm glad you enjoyed it and shared your experience.
