Today was a typical summer day in Oakland. The fog burned off by late morning, the sun shined in a cloudless sky for most of the day, and then the fog returned before sunset. The shoreline grass along the estuary has turned a wonderful golden color, which seems that much richer against the blue sky. The sunlight made the water sparkle. In short, it was a beautiful day.
