I don’t usually do these—where there’s nothing left of the postcard scene—but it took me so damn long to figure this one out that I’m writing about it anyway. I give you: the old Exchange Building at Chicago’s Union Stockyards and the Exchange Station on the Stockyards Branch of the L. Once the brains (the Exchange) and the veins (the L) of the world’s brawniest slaughterhouse district, it's now a random intersection in an industrial park (which is okay [well, mostly—that L would be nice to have]! the stockyards were hellish for people and animals alike and the model was obsolete).
