Golden Gate Bridge, San Francisco

I've been quite lucky - every time I've visited the Golden Gate Bridge the weather has been great! On this particular day in September, the sky was clear and blue as we were walking around Macondry Lane. Then all of a sudden, a huge bank of fog came out of nowhere (not an unusual occurrence, apparently) and completely enveloped the bridge and the bay. We rushed off to the Marin Headlands to get a view of the bridge in the fog. Unfortunately, the traffic was a little heavy so most of the fog has disappeared by the time we got to our vantage point. Oh well, we still managed to get some very nice pics.
