Sorry harris7 but the interesting traits about the crop circles have be pretty thoroughly disputed. As I mentioned above-I watched a college student plot one out on his computer, pick the field and the date he would do it...send his plans in a registered letter so the date and design were verified before the circle was made. He created the circle in about four hours with the help of a couple of friends (filmed themselves doing it)...a very elaborate design with all kinds of physics and math to make it interesting.

Within a few days after he made it, all the researchers were there claiming there was no way the wheat could be woven like that, etc...they were out there with geiger counters claiming radio activity and all sorts of paranormal phenomena. When confronted with indisputable proof that the kid made it, they absolutely refused to accept accept the truth.

UFOs are a phenomenon. But they have very little to do with real aliens as they are a cultural anomily. Aliens and bigfoot are replacing the Angels and demons of yore in our mythologies. It tells us something about ourselves as humans...that's what makes it really interesting, and that's the real mystery that everyone is missing.
