There is plenty of research out there right now that indicates that even the hoaxers feel like they are being "guided" to make a certain formation. What's even odder, is that... at times, they have drawn up a certain pictogram and not been able to get out and make it that night; yet it will still mysteriously "appear" the next morning in the field they were planning on using. Plenty of these unusual stories abound, including even odd electrical malfunctions and failures in man made circles. It tweeks one's mind to have a closer look at these things, without just totally dismissing the evidence outright.
