Be sure to investigate the stickies at the top of the page. There is some terrific advice "For Those Driving."
When we drive from NE CT we like the alternate (but longer) route of 81-84-77-26-95. It's far more scenic, and an enjoyable drive. We have had terrible experiences with DC traffic even at 3am! Plus stop to enjoy NC rest stops. Next to some in Iowa they are the best we've seen.
