I saw a documentary on Tenochtitlan. This is the n. side of Mexico City, fantastic pyramids built long before the Aztecs, by a mysterious race of Indians. As they have excavated these pyramids, they have learned that the city was so wealthy because it sat on a mother lode of high quality obsidian. They made all kinds of points, and also traded bulk obsidian all over Mexico and Central America. It would be as though, 200 years ago, yours was the only country that had a good supply of iron ore.
So, 1minute, you would have been right at home a thousand years ago in Tenochtitlan.
