A friend and I are driving from Los Angeles to New York in early August in a Prius. We have 6-8 days. We are driving to Sedona the first day. After that we will be following I-40 to I-81. What I am particularly interested in are specific places to get off the interstate and drive for a couple of hours on more scenic roads (e.g. Route 66 and Blue Ridge Parkway). For time purposes we have to largely drive the interstate so I am looking for suggestions for the best places to exit and then reenter the interstate for short side travels that will still keep us generally headed in the right direction. Many thanks. I have learned a lot from this website in planning the trip.
