Russ, I was there twice in 1971. I believe the first time was either late June or over July 4th. The second one was over Labor Day. The first visit they had the box car coaches as well as the second. If I remember right the first visit only had 484. They ran trips to Sublette from Antonito, then backed to Antonito. Not sure if there was a turning loop at Antonito that first year. Anyway if I am still here when 2021 rolls around I will post a bunch if I ever get them scanned. I believe a few were those dreaded Agfa slides!!!
