If you’re like us, you’ve spent many a seminar playing “guess the biggest secret of the person sitting next to you.” We’ve concocted a twisted past habit or two, but we didn’t think of naked urban spelunking until this article in the Times today provided us with ample imagery. The piece has weird Pupin lore, overt fetishization, hip post-industrial aesthetics, “human vulnerability,” and all the rest of what you love. Thanks Nick Kelly for pointing it out.
