In Utah, we saw a double rainbow. Those were the most gorgeous rainbows I have ever seen. One of them you could see the whole thing from one end to the other. It was incredible. I am not sure I have ever seen a full rainbow before.
Here are some picture Michael caught of them. You will see in the second picture the faint double rainbow. If you click on the photo, it will take you to a bigger view of it.
