I saw a show on the Discovery Channel where these guys showed how they make crop circles, and they were just that CIRCLES. They had wood planks that they used to lay down the corn stalks in a corn field.
I’m not real sure how they would do this in one night…..
No mistakes are ever made, and no imperfections of geometry are noticed. Pretty good work whoever is doing it.
At least I can say “I don’t have any idea who is doing it.” And I am not foolish enough to think I have the answer.
