SF has its own major problems with transportation.

Has any of you taken a MUNI bus lately?

They don't even have enough vehicles to bus those within SF, let alone them worrying about lines running outside the city to the airport.

Try waiting 20 mins. for a MUNI bus. When it gets to your stop, it is full, so it won't stop. You then wait for the next one. Problem is that the next one is jampacked as well. If you're lucky, you squeeze on. If not, that's another 20 mins, for a total of 1 hr + at times.

This wasn't so until not long ago when the city claimed they had budget issues and made transportation cuts.
