Over rehabilitation

We can't help it. We rehabilitate to "first class", then let it age for 5 to 50 years so that it becomes "authentic"; somewhat matching photos in the history books. Oh, we'll have to carefully add litter. This was written with tongue firmly planted in cheek.
My wayside maintenance station experience has been at Cumbres and at Sublette. At Cumbres, the paved highway, which eliminated the station, the big (and well appreciated) parking lot, and the radio relay station on the section house prevent this area from ever being authentic. The recreation of various structure foundations is quite acceptable; they will look even better after a quarter century of "weathering".
At Sublette, we've been careful not to litter. Maybe we should develop some non-flammable "litter" on our last day. There is a viewpoint maybe a couple hundred feet east of Sublette Heights. Look for large rotted log. I recommend it, especially if a tender is being watered. Lack of grafitti is not obvious from that distance.
