I really love big, concrete grain elevators (Wow, AGHRMAtt - 2000 feet!) - in addition to just being very impressive on their own right, they look like an ammunition clip for some impossibly big automatic gun or something. Growing up in the west/mid-west I saw a lot of them. I don't really have room for one on my layout. I might be able to fit one as a shallow backdrop in - would love to, but I'm not sure I have even enough depth for that . . .
Here in NC, where we live now, we have only a few big concrete silo elevators - I see them from time to time but not nearly as many. We have a lot of sheet-metal oines as in the photo below, nice no doubt, and probably fun to build as a model, too, but just not a "grain elevator" in my world . . .
