Some years ago (maybe around 1995??) when it was not considered a death wish to travel to Mexico, I had the good fortune of going to Cancun, with a trip to Chichen Itza on the itinerary.
I have never been much into archaeology or related, but I found Chichen Itza to be fascinating, and the visit there remains one of my most vivid memories.
Is it true that the Aztecs, Mayas, and so on never figured out how to make a WHEEL???
