Hell Skee I have yet to strictly stick to a planned route, mine are more of a ...guideline to areas of interest. 
That pretty much makes it unanimious (I said maybe...)
You up for riding 12 O'clock Knob Road again?
Hmm...what is this "12 O'Clock Knob Road" of which you speak?"

Go to Google Maps and type the search string "12 Oclock Knob Rd, Roanoke, VA". It might auto complete as "12 O'Clock Knob Road, Salem, Roanoke County, VA".
I used it to go from 311 to 221 and the BRP by spending as little time in Roanoke traffic as possible.
Beans & I ran into 2 local cruisers at a roadside stop on the BRP who asked us how we got to the BRP. When I mentioned 12 Oclock Knob Rd, they told us that you can't take a motorcycle over that road. It's too narrow, the crown is too high, the shoulders drop off sharply and there are potholes and loose gravel all over the place. Beans had to tell the guy about 3 times that yes, that was the road we just came over before his jaw dropped. I still don't think he believed us.
Not scenic or all that interesting; makes a better story that a shortcut. I wouldn't go seek it out unless you are looking for a technical obstacle course. (Then I'd take some of the roads up to Red Knob.) But we both agreed it was fun. And would probably do it again.
