Greg,
Your third frame is right around MP 317.1.
John's photos and Russ' photo are taken from MP 316.15. The RR has bulldozed a wide spot on the outside of the curve and you could get a large group on the ground there. John's fall color shot is aimed to the right of his first shot. You can match his shot and Russ' although Russ is shooting much tighter. The only thing wrong with that location is you would need to back up almost a mile to do the runby.
The red X marks the spot where the photos were taken.
