Disney Making Fake Crop Circles?

GuNgA-DiN writes: "It seems that Disney has been busy trying to promote their upcoming movie 'Signs' (by M. Night Shyamalan). There is an interesting article from some guys who REALLY follow and study crop signs: Paul Anderson of the Canadian Crop Circle Research Network has reason to believe that they will be creating some man-made formations to promote the forthcoming movie. Anderson cites a competition or sweepstakes currently being promoted on the official 'Signs' website." Remember, patronize only genuine alien-swirled crop circles!
