A New Spin on Crop Circles

                              REALLY!?

This ad picture from an irrigation pivot company implies that this pattern of irrigation center pivots goes on for a while, and should be replicated everywhere possible.  Well, I don't know many places in the world where this kind of concentrated water use would be all that intelligent.  There probably are some, but not around my neck of the woods.  So, wherever this photo is, I'm guessing there is a local water supply under some level of stress.  Well managed irrigation development is a good thing, but limits to that development are exceeded more often than not, which stresses the water supply - be it ground or surface water.  I personally think the ad would have been just as effective if a more reasonable pattern of pivot development had been selected.  It would seem more intelligent to me, anyway.
