I can just see that view now, you sticking your head out of the sunroof with the camera to get the shots! lol Doesn't sound very safe in the end though!

Too bad you can never actually get to the end of the rainbow to find that pot of gold... The closer you get the more they move! They are beautiful things, and always fun to see. I love the double rainbows as well, you don't get to see those quite as often.

Have you ever seen a moonbow? I've only seen one once, they aren't bright and have no colors, but they are interesting.

I can't say that I recall the song from the Wizard of Oz either, being a man I'm not much into musicals. Even the classics like that one. But in the end you are correct, we can't ever get to that pot of gold at end of rainbow or catch that falling star. Just things of natural beauty we can enjoy, and such is life!
