1968 NPS Tour

November 24 & 25, 1968 were the dates that the National Park Service toured the D&RGW from Durango to Alamosa. I am trying to fix the location of some photos in our collection and would like to know if someone has a copy of a Trip Report or some other document that contains a detailed itinerary for the trip including locations where the train halted and passengers were permitted off to explore the site. I have some documents but they are mainly works about possibilities for the line. Also I am curious as to who paid for this trip. Was it the D&RGW as a seller or the NPS as a potential buyer? Thanks for any additional information. -- Wes
