Serpent Mound is a neat place. There have been many theories on what the mound. I had the pleasure of volunteering for a while and fell in love with the mysterious place that feels sacred. Get out of the city and go to this part of the country.

These Crop Circles appeared at Serpent Mound in June of 2003. One has been confirmed a hoax. I visited the smiley face looking circle. Very neat! When the crops were harvested in the fall, guess what? The image was burned into the soil!
