ray,
we went from s nj (through Lambertville) to portland, maine by an alternative to ACA route, though there was some overlap. we used the route Donna Lynn Ikenberry designed (goes through cape cod) entitled "Bicycling the Atlantic Coast, Florida to Maine" (isbn: 0898863031). friend rode up from S Carolina, we met, he went on to Nova Scotia then returned (same route) to charlotte, SC! if i had the time........... ACA route is more inland, ikenberry is more seaward.
have fun!
