Thank you sooooooo much for tickling my gray cells. I did some internet research and this vid popped up. It tells that there had been a civilization in the Grand Canyon for a long time. Pretty convincing evidence that an Eastern civilization was present and they dug some massive structures into the bank of the canyon. I wonder where this would lead to. Probably somewhere Americans would not want to know about. Once again, thanks for the prod.
