Ever since I saw my first train layout in my youth I have always been fascinated by a world in miniature. I don’t know why? Maybe it is a God complex.🤣 I have dabbled with making my own several times but never managed to get very far. I guess I like the “idea” of a miniature layout more than the work required to make it happen. Anyway, when I came across this HUGE layout at some museum in Chicago it blew me away. I don’t recall the museum now, maybe someone can help me with that? I don’t really think there are many mountains in Illinois, so maybe that is artistic license. But it does take a large layout to depict the Illinois farmland.
