94309 [nien·for·three·oh·nien] n. this is the University's ZIP Code, each number is spoken individually in the mode of the title of a popular 1990s television show (Beverly Hills, 90210); the inference being that Stanford is so large (owns so much land) that it needs its own separate ZIP Code. *note: A well-known insider joke goes, "There are 4 million bicycles in California and 3 million of them are at Stanford." (This is simultaneously commentary on the popular culture idea of sunny California's collective overzealous love of outdoor activities like bicycling, the University's immense acreage, and the fact that most of the inner University campus is closed off to motor vehicles, so bicycles are the default mode of transport to crisscross said immensity.) *ref.: because of its substantial land ownership and its status as a private university and a nature preserve, Stanford operates as its own municipality in many respects.
