Today I went (with grandson Jason) on the complete route. Conditions were good, and we made good time, with little interference. We left the hotel at 9:30, and arrived at the lunch site at 11:30. We spent an hour at lunch, got gas, and made it back to the hotel at 2:00, again making good time. So there would be plenty of time for afternoon activities.
I must say, this is a very nice route. Plenty of curves, and very little straight. The small amount of dirt road on Doublehead Gap was easily drivable by Fiero.
I can't guarantee that conditions will be as good on the actual run day, but we can hope.
This was the revised route by Fierofool, which included 19/129 over "Blood Mountain". On that stretch, there was a F150 behind me who was managing to keep up, amazingly.
