That link is particularly worth seeing, however, in the context of this recent interview with Stanley Greenberg, published last week on Urban Omnibus. As Greenberg says, “I think the city is a huge organism, only some of it visible, and we inhabit it, change it, get changed by it. But there is so much of it that I don’t know”—so much of it still undiscovered, including infrastructure often invisible for the fact that it stands proudly in plain view.
