For me this article contained a Ghost Address: the Ogden Drive swimming pool highlighted in the article is located just a few buildings south of a place I lived for four months in 2007. It was only four months because I unexpectedly applied to and was accepted by Y Combinator, and thus had to move to the Bay Area on short notice. Nevertheless, I walked past that building dozens of times—never seeing the oddly shaped pool, never knowing I was walking past a ghost.
