Have been looking at Richmond for a base, with daily trips out to see as much as possible. Daily driving is good, but across the country, not so much. Planning continues. Thank you all again for the hints!Anything in and out of Dulles IAD cost more according to AAA when they recently rated all the big airports around here. But Dulles is convenient to me being a half hour away (if the traffic is problem-free); the long term parking is cheaper compared to Reagan or BWI. Richmond might be better it you want to visit Luray and then drive up through the Valley.
