I've got a trip planned with a buddy of mine to do the Blue Ridge, the Dragon and Cherohala next June.
I rode a section of the Blue Ridge and the Skyline Drive last year, and I'd point out
that any road is easy if you keep the speed down. The challenge comes when you turn up the wick enough to keep it interesting, but not so much as to be overly risky. (a big part of the challenge is to know where that line is) . I found the section of the Blue Ridge wouth of Waynesboro, Va to be quite entertaining on the GS.
