there are crop circles and there are crop circles. some of these things show up in a matter of minutes and they are so amazingly beautiful and complex that it blows the mind to think anyone could do that with some planks and string after a nite at the pub. sure there are shity man made crop circles, but some of them are very different, don't ask me what they are or how they come about, but when those pub guys were asked to make more crop circles with their tech the results were abysmal and nothing at all like some of the "real" crop circles one can find being documented. there is a whole community dedicated to watching certain fields and informing everyone as soon as a new one apears, these guys documentation is pretty compelling. apparently the earth under the circles is actually altered and they find tinny metal spheres in the soil samples. also the crops them selves are changed in a strange way, the place where they are bent down seems to look like it was a piece of corn in the micro wave, very interesting.
