Fog, In Los Angeles!

Fog!  In Los Angeles!  What?  We were at a museum today several miles inland from the ocean and it was blue sky and sunshine.  At the end of the day we were driving back toward Venice, and saw towering clouds which gradually obscured the sun as we got nearer to the beach.  By the time we got home, it was dense fog everywhere!  I was out photographing these trees, the larger one is in front of Amy & Gus' house.  A man was walking down the street toward me, and he kept looking behind, apparently wondering what I was photographing.  When he got closer, I said I was photographing the fog.  He said "Oh. I am from San Francisco and fog is not a big deal there!"  I explained that I had never seen fog in Los Angeles before.
