Rainbows are beautiful. Double, or single. Once I saw one on the highway over from a road – the end of the rainbow – it was huge – that one end spread fully across the whole lane. True story, and the first time I’ve ever seen the end of a rainbow. Smaller rainbows can even be seen high in the sky, whether amongst clouds and sun, or, on a day that is essentially clear, but where there must be water droplets up above.
