With each passing yr these things become more beautiful, precise & complicated to be made by a couple of pranksters in the middle of the night using boards & twine. Farmers often just plow them under rather than report them and deal with the crowds of people that will invariably come. Seems like an awful lot of work for pranksters to go thru if it ends up that no one sees it. This one makes me think it represents something to track time & the universe. Is someone or something trying to teach us something? What say you?
