Bobette, amen to that. It was scary enough going just north on Hwy 550 to Montrose from Durango. I can't imagine doing it multiple times. However, my neighbors (who told that the hwy was a must do in Colorado) apparently have done it numerous times.

JerryFF, I know there is a road that goes out of Marble and ends up in the Crested Butte area. I am not sure how good the road is but heard it was very scenic. I did drive up to the entrance of the marble quarry (single lane dirt/gravel road for 4 miles). This was in July and absolutely gorgeous.
