I missed NAFO - don't ask - but when I was up there a couple of weeks ago for the MTF run, I did a loop of NC29, US129 (Deal Gap and beyond), TN72, US441, TN360, TN165/NC143 (Cherahala) through Robbinsville to Stecoah and Ironhorse Lodge.
During that ride I was passed 3 times (!) by a pair of sport riders on a Speed Triple and an unknown model Honda Repsol replica. I'm old and slow, encumbered further by a Gen 2 but was keeping a decent pace; these guys would get ahead of me then stop somewhere (I would see them at places) and down the road, here they come again.
I'd just move over and motion 'em by. They were smooth and had good lines IMO, and I think, especially later on, they recognized me and knew I would let them by when it was safe - which was as soon as possible. I kinda wish I had stopped one of the times I saw them and introduced myself.
But, I came several times on much slower bikes of, ahem, a certain manufacturer, and while I don't like to stereotype anyone, it sure seems they not only liked taking up the whole road, being loud about it, but the heck with anyone else that wanted by, even an old slow guy on an FJR...........
