Forest Road 1023
If it was wet at all I am sure you had your work cut out for you on such a large bike. I road up 1023 last summer on a DR650 with Trailwings and it was a little sloppy in places. An extra 150 pounds would probably have made things more interesting than necessary...
When you mentioned Nebo Mountain Road, were you talking about the Virginia gravel road that more or less parallels 16 to the east from 42 down to Marion? Or are you talking about NC 80 that runs from Nebo/Marion north to Loafer's Glory?
