Where in the world?

If you read this Blog at all, you probably realized that I was displaying selections from my huge collection of photos. I have traveled extensively in the U.S. but not much abroad for the last few years. I will give you one clue to where the above picture was taken, it was taken in Arizona. I didn't know Arizona even had a place this this. But if you look closely at the picture, you will see tell-tale indications of its location.
