I tend to take an esoteric view of places such as this. I personally feel there is intrinsic power in these sites, and that is why the ancients built things such as mounds, pyramids and other structures/glyphs in these locations.
I have heard people locally say there is nothing to do where we live. Nothing is further from the truth. There are over 300 mounds in Ohio (and there used to be thousands). The ancient structures are a fascinating and renewing resource that you owe to yourself to visit.
I walked away from this trip changed in some way. I think my kids did also. The conversation on the way home wasn't about video games, soccer, what to eat, etc. It was about what we had just experienced. My own problems faded as I realized what we had seen was much older than us, that many generations have passed and yet, this effigy still remains, to tell us a story of the past. Perhaps of the present and future.
There was no whining about never having been to Disney, or about things that they perceive that they don't have. Both were talking about what they wanted to do when we go back.
I am thankful that I can share this with my kids. So much time is wasted watching TV, playing video games, doing nothing. Time, unfortunately, is something we can't get back. I intend to take advantage of that which I have.
