Because there was a traffic jam

[nikonf3]

Before the beginning of summer, we were in Sacramento on some errand. They were (and still are) doing major work on the I-80 freeway and we found ourselves stopped at a place where things usually move at 100 kph. So I got a shot that is usually impossible. We’re crossing the Sacramento River. The camera is facing east. On a clear day in winter, that horizon is a line of snow-capped mountains.
