Just a silly question, but why would anyone ride 40N between Morrison and the parking lots (tight two laner with a ton of fast moving traffic while you are climbing) instead of going down to the C470 frontage road (No traffic, wide open road)? I know there is a difference between riding in a great canyon and riding along a freeway, but its such a more relaxing way to cover that span.
Now, 40S when you are flying at close to the car speed I can understand, its fast and fun, but coming up from Morrison, no thank you.
I'm making the gross assumption that you are going up Lookup at the beginning, which would be the only sane way to ride this route, but one nenver knows.
I digress, its a great route, have a great time, the ride down from Evergreen is soo nice.
