Interestingly, I am currently in Asheville NC, and have been exploring the Blue ridge Parkway for the past few days. Unfortunately, I don't have my bike with me this trip (not really the best time of year for it as far as I can tell,) but I plan to come back some day on 2 wheels. Incredible vistas, Long winding roads and sweeping curves. I think fall would be the most picturesque, but I hear it is also the busiest time to be here.
I have also had the pleasure of riding and driving on both the San Juan Skyway in Colorado, and the Beartooth Highway from Wyoming into Montana.
