I was at the gas station waiting to fill my car when I looked up and saw this view up the hill.I watched the scene develop as the clouds moved from my right to the left to provide some covering.Quickly I grabbed my camera and took a shot in live view.Did some cropping for size for publication and post editing to enhance contrast slightly with Digital Photo Professional.
