Negative Green and Easter Island

[Peregrinus]

Interesting. On the reference, on the page you linked, to crop formations... I would note though that having been in man made and other made crop formations, only the other made had an effect on me, whereby I heard an excruciating shrill sound which caused a splitting headache. The sound continued for about 24 hours after leaving the formation, and the headache continued for 48 hours. The sound is actually how I found it when others were looking, I pulled over and said it is right there over that hill to the left.
