Very very good point.
The circle that started this thread is obviously some kind of tribute to, or promotion for, the new Mel Gibson movie, imo. We went from the early to mid 90's until basically now without hearing about any crop circles (after those 2 guys in England came forward with their story and explaination how they did it) and suddenly now there are more circles, just when Signs (the movie all about them) comes out?
If that's just a coincidence, then I'll resign my FR membership (much to the delight of some I'm sure, but that's how certain I am that it's not a coincidence).
But then we'd know!
Actually, I keep waiting for him to break down and start posting in blue.
