Playing golf while it's pouring down rain isn't that fun unless like me you get an extra kick from the increased difficulty of a wet grip, chips that die in puddles, and divots which splash in your face.
Just when you're about ready to give up, the skies clear and you are given a message from one of the golfing gods.
It is a beautiful rainbow off in the distance showing you where the next hole is. You whisper to yourself how much fun it would be to make a birdie under that multi-colored arch of light, and you're off to make it happen.
