I was up working in the Bay area and flew over the City of San Francisco. On a clear day, you can see downtown San Francisco, the wharf, Alcatraz and the Golden Gate Bridge all at the same time. I don't think you can take a bad picture of SF on one of these clear days. Here is a picture of downtown San Francisco and a close up of Alcatraz prison.

Also, here is an aerial video of downtown San Francisco that was shot on the same trip.
