re: Knotted Wheat in Fields
In the hood indeed. The locals who know some of the hoaxers say some of them are on drugs and there's a lot of in-fighting among themselves; even up to fisticuffs.
If podrock is right, and some of those nested circles could be done with a broomstick, you have to wonder why anyone would risk their hide and fines and imprisonment to do such a thing. They must be getting something out of it. It looks difficult to do in the dark.
Seeing as the formation was cut out within hours, (the farmer didn't approve), and if enough of them complain; the hoaxers will soon be stopped for the criminal damage they are doing.
