The End of the Rainbow
From the OCRegister:
UPDATE (Monday, 5:23 p.m.)
...Several readers have said in the Comments section that they think this image was PhotoShopped. Nick: But it appears that this image is genuine. I have now had it reviewed by 7 people — 3 veteran photographers, a top-notch graphic designer who specializes in PhotoShop,m and 3 meteorologists at the National Weather Service. We also uploaded the image to Flickr and checked the lat/long of the image, which was taken with an iPhone. The info box says the photo was taken where the reader said it was taken. And the info text says the photo was not manipulated.
So why not a little "She's a Rainbow" (World of Twist cover):
