I love San Francisco- and I love it's fog. 

This gorgeous video titled Adrift, is a “love letter to the fog of the San Francisco Bay Area” that shows a whole different side of the famous weather pattern. 

The video was made by photographer Simon Christen. He explains to Treehugger what it took:

The weather conditions have to be just right for the fog to glide over the hills and under the bridge. I developed a system for trying to guess when to make the drive out to shoot, which involved checking the weather forecast, satellite images and webcams multiple times a day. For about 2 years, if the weather looked promising, I would set my alarm to 5am, recheck the webcams, and then set off on the 45-minute drive to the Marin Headlands.

I spent many mornings hiking in the dark to only find that the fog was too high, too low, or already gone by the time I got there. Luckily, once in a while the conditions would be perfect and I was able to capture something really special. Adrift is a collection of my favorite shots from these excursions into the ridges of the Marin Headlands.
