One site they featured on an episode is the Georgia Guidestones, also known to some as the American Stonehenge. I'd never heard of this site, which opened in 1980.
You know, it's really sad how there are so many people out there who can't just enjoy the fact that there are still some mysteries out there. Some people are claiming the monument is a sign of the Anti-Christ and that it's pushing a New World Order. Some people have actually defaced the monument. Regardless of what your feelings are on its origin or meaning, I think it's cool, although odd, that something like this was erected in our country under such a curtain of mystery. I think it's neat that, hopefully, some time in the future people might look back at this monument like we look at Stonehenge or the Nazca Lines and try to decipher it.
It's nice to know there are still genuine, albeit benign, mysteries out there in the world. (And yes, I feel a story germinating in my brain. LOL)
