Doves:
 
I saw a beautiful cloud formation yesterday with an open door right in the center, but the door was shaped with an ARCH at the top. Didn't have a camera with me at the time to capture it. It was about 830 in the evening just as the sun was setting. It was beautiful! The door was a totally different color than the clouds around it. They were darker in color - the door was a light blue with a glow in it.
 
Maranantha!
