I grew up in Durango but have never been to the Festival in Telluride. I DID go there in the 60's for the 4th of July.....a slightly different period in the life of Telluride.
Oh, what happened to your photos? A shame they are not showing up, perhaps a problem with the host?
PS, while you were riding towards Durango from Silverton, you should have taken the Lime Creek Road. It is the original route of 550 from just north of Durango Mountain Resort (previously known as Purgatory) to the foot of Molas Pass. A great dual-sport road!
