San Francisco's fog is a lively, fluid, beautiful thing that keeps our midsummer beautifully moderate.
Michael Winokur has put together a video showing our fog illuminated by lights, by sun, from above, from below, and (my favorite thing ever), as it pours like cream over the ridges of the Peninsula and Marin Headlands.
I found this via Sutro Tower (no, really - the Bay Bridge also tweets, I love the internet) on Twitter.
