I admire your interest in other cultures! It is so nice to see other people who are still traveling, exploring and learning. Many of the people I know are content to get their culture from television. :( YOU got to see glow worm caves in person. It simply does not translate very well on TV, does it? Here in Oklahoma, there is a lot of culture, and a simple web search will turn up all kinds of centers for discovery. I just heard about the Fort Worth Native American Museum for example.
