The fog had already come in this evening when I saw this sign at Potrero & 16th in San Francisco and stopped to take its picture. I was on my way home from the gym, intending to walk. But with a cold ocean wind in my face, I was not sorry either when an empty bus pulled up and I could jump on it and ride home instead. So I thank this sign for causing me to pause in admiration long enough for the small but happy accident of the bus to occur.
