We walked out of the theater on Thanksgiving afternoon and it had been raining while we were inside. (We saw Skyfall, which was great!)
As we got closer to the car I noticed a small group of women with their camera directed to the sky behind us and I turned around to see this rainbow. The sky was dark to the east and clear to the west, and the rainbow was really bright going into the dark clouds. I was able to get this shot through the windshield as we drove away.
A Thanksgiving rainbow must be a good omen, right?!
