Rainbows have long been associated with good luck or good fortune and have a way of brightening the day. I captured this one shortly before sunset last week. If you have ever wondered why sometimes you see a rainbow after the rain and sometimes you don't, you may be interested to learn that rainbows are only visible in the morning and afternoon because when the sun is high in the sky the rainbow appears below the horizon. So, if you are into rainbows, look for them after showers in the morning and evening, not when the sun is high in the sky.
