Nice picture, Glen. I am hoping to make a trip to Colorado this summer, and thought about swinging by Tefft Spur to take a picture of this boiler for my "Surviving World Steam Locomotives" project. I don't think this "flat-lander" could handle that three-mile hike over that terrain at that altitude, however.
Thanks to everyone for your feedback to my original question. It looks like it is weathering very gracefully.
