Heh heh heh. It's a federal government department.....
Oakland airport isn't far from anywhere in that area, but you need a car. I would be more worried about driving in san francisco city than flying over it
You can take the BART but it's not the best area when you get to Oakland.
Calling it San Fran is better than calling it Frisco, but not much. If you want to be considered cool call it The City!
