This was one beautiful drive! I drove from Portland to San Francisco when I took this photograph. Immediately after the border between Oregon and Portland, scenic route one starts; I almost missed the intersection!
It is quite dangerous to drive there – no street lights and barriers for animals. I was driving slow to not run into possible animals crossing the street.
When taking photos at a location, just stay longer than you really wanted. Or go back to the same location during different light conditions. You may find some different cloud and light constellations when getting back to the same location at a different time.
