We had our honeymoon in the area, and spent quite a bit of time on the Dragon. Fantastic road, but there are other (arguably better) roads in the area with WAY less traffic/attention. It's a beautiful area, with the Smokey Mt. National park nearby and plenty of things to see and do. WELL worth the drive.
