| Yeah, many of these transit systems run through a lot of different cities. The BART system in the San Francisco Bay Area goes to Millbrae, San Bruno, South San Francisco, Colma, Daly City, Oakland San Leandro, Hayward, Union City, Fremont, Castro Valley, Pleasanton, Livermore, Berkeley, Albany, El Cerrito, Richmond, Orinda, Walnut Creek, Concord, Pittsburgh, and Antioch (and that's probably not a complete list). So why is only San Francisco counted. The DC Metro system is the same way, serving a bunch of cities in Northern Virginia. |
