I don't have a photo, but I have a question.
Years ago, we were on a family weekend in the Ironbridge area. As we drove into the town of Ironbridge, it rained, and we saw a very good rainbow, which seemed to come down in the middle of town before it faded.
When we got to the spot where it had seemed to be, there was a gift shop called "Rainbow's End". Freaky, or just common coincidence? I've always wondered though if there are some places more prone to rainbows, although I can't quite think how it would happen - topography affecting prevailing cloud patterns or something....
