Late this afternoon, there was a fantastic complete arch of a rainbow in the Wendover area of Rural Buckinghamshire.
At the time I was sat on a Chiltern Railways train. The windows were fairly grubby and trees and bushes a plenty, as we bimbled along. This was the best I could do, and not even with a proper camera.
Darrell Jordan has a much better picture of the same rainbow taken at nearby Little Kimble.
