Traffic streams across the Golden Gate Bridge as twilight fades to night. Work is over, the day is done and everyone is in a hurry to get home or to the stores for holiday shopping. There is no divider between the oncoming lanes of traffic and the lanes are narrow. Only small plastic cones divide the traffic as cars weave back and forth from lane to lane trying to get one more car ahead. High above remnants of the days storm clouds blow southward and catch the last glow from the setting sun.
