I love the fog in Southern California! One time when I mentioned that on some other little social media site, I had a bit of a heckler who thought I was crazy. Their mental image of fog was from down by the coast, where it was grey and blocked out the sun. But the thing is with a little change in perspective, just a five minute drive up in the hills, the grey mist takes on a whole new look.
When the weather is just right you can get a clear day with a beautiful blanket rolling in over the city lights and the result is amazing. Once you change your perspective you'll never quite look at things the same again!
