Yep. Sorry, but you can't get away from the sky out here. Even if you wanted to. The Lakota and the Cheyenne were very aware of, and had great respect, for the sky. How could they not, living here in the Home of the Sky-beings?
This rainbow is from last night. Another fast-moving thunder storm came through and then there was sudden clearing. Shortly after this picture was taken, looking due south, the sun came up and flooded the prairie with bright, golden light and the rainbow slowly disappeared.
