  1. That video is pretty awesome, the part where they look at pools and purposely draw the wrong conclusions was hilarious. I traveled around Mesa Verde and it was so incredible, and until I actually went there I didn't associate epic ruins with North America.
    Its interesting to see the problems past powers faced, which ones they overcame, and what led to their ultimate demise.
