Today while walking the dogs; include 3 puppies, Kamik and Kai, we saw a shifting rainbow.
It arched into the dark rain clouds, and out the far side. As we watched it continuously change we noticed the end of the rainbow.
It came down the side of a hill to a house. The hillside was rainbow lit, most predominately yellow and pink, then amazingly it moved forward to the road and the road was rainbow lit.
The far side gave us a second rainbow they shifted in brightness before disappearing.
Now we know where the rainbows begin.
