Why is it so hard for people to believe in u.f.o.'s and their connection with the circles? They've been a constant since the beginnings of recorded history. Don't worry, I know I sound like a nutbar but I don't care anymore. So much of what we've been told in the past is the truth, turns out to likely be erroneous. Take the creation of fossil fuels as an example. Dinosaurs and plant matter, vis a vis the term fossil fuel, is under much scrutiny and from what I've read, likely not the origin.
I suppose that the antelopes will be blamed as their migration patterns have been affected by the change in the magnetosphere, but I'll stick to what seems more likely than not. Not all hoaxes so some other intelligence that can microwave from above etc..
