I was in San Francisco, jetlagged and grumpy.
It was 5:30am in the morning when I went out for a walk, and then my day got much better.
The sun was rising, the city was bathed in gorgeous golden light, and I had gotten to the waterfront, which was alive with people.
This appears to be a running pier. The main subject of the photo, runs back … and forward…. and back… (you get the idea).
