I love light trails from cars at night. They somehow add so much more life and detail to the photograph. I took this photo about 30 minutes after sunset on a cold October night and only expected to capture the silhouette of Monument Valley. Then I heard a car coming from the north and decided to leave my shutter open. I was left with an awesome but short light trail from the car's rear lights. Inspired, I waited about ten minutes for the next car to come and was left with this treat.
