But with fireworks instead of human sacrifices.
I've seen fireworks before and I have some extra vacation time. So where do I go to see a human sacrifice? Its a short hop from Houston to Mexico City.
Well, Mexico City wouldn't be Mayan, but you could run out to the Pyramids of the Sun and Moon, and see if the Teotihuacanos were holding something in their area. Don't think it's known for sure if they used the Mayan calendar, though.
Otherwise, you could try a short hop to Chichen Itza, although my personal fave would be Uxmal.
