Every picture of a crop circle I have seen has been flawless. It seems to me, that if they are made by man, or even otherwise, there would be some crop circle malfunctions. Many of them are intricate and precise, and the slightest miscalculation could spell disaster for the whole thing. But, I have never seen a picture of an f'd up circle, half an attempt, a practice run, or any other anomalies. They all just look too good. Or did I miss the ugly/f'd ones?
