Welcome aboard the RoadTrip America Forums!

Where to stop would depend on your (and your grandson's) interests and how much time you have for the journey. A "more scenic route" would depend on comparing it to what you're already planning. Without those details, we really can't offer you more than generic (and therefore useless) hints. With them we can give you the kind of help that might make you a bigger hero to your grandson.
