I realize this is a common question, but I am not finding anything current. So forgive me.
I am flying in from San Francisco mid-week in early Oct. - touch down about 10:00 pm (ish). Will there be shuttles circling the airport for transport into the City? I don't want the hassle or reserving a shuttle, but if there is one I can hop on, I'd rather save $ by using it rather than a cab.
