I'd note that the Atlantic Coast Route is a coastal route rather than going through the mountains.
A good point, Peaks. Janie, there is plenty of color in the coastal areas, usually a week or so later than in the hills of the same latitude, but most leaf peepers want the hills. If you have never experienced fall foliage, you might want to bite the bullet and make advance reservations to see the show. A bike is the best way to see it, and the ACA route keeps you off the big roads with their tour busses from Nebraska.
Call some of the places on the route and ask how much notice they need for a particular week or weekend. In the heavy tourist spots (think Stowe VT) many of them want a two-night minimum on foliage weekends. I have found innkeepers to be very helpful. They like cyclists, who eat a lot and go to bed early.
