The Kankamangus Highway near Conway in New Hampshire is one of the best in the U.S. Watch out for moose crossing the road, though.
I agree, it is a great road - However ... You'll need to hit this at about 6am to really enjoy it - anytime later it is laden with campers and inanely erratic looky-loos.
While you're in the area make sure to hit Frankonia Notch
Ride up Mt. Washington
And of course stop for a tasty breakfast in Colbrooke
