Paul, I only have one friend who is interested in the Montrose area: Ourayman Steve, an excellent modeler who models Montrose to Ouray, both HO and HOn3. He has done extensive research on Montrose including running down pix owned by ancient people and descendants still living in the area. If I could find a way to PM you, I would give you his email addy.
Besides Ridgway, I'm doing the line up to Ouray myself, since I have the space, and need sidings to park rolling stock, but lucky for me am doing the late version of Ouray after much of the track was removed and the depot had burned down. jefe
