I live slap bang in the middle of crop circle country and this seasons first arrived last week. Most of the farmers can't stand the destruction of their property and have started resorting to cutting the circles instantly in the hope that it deters people from trampling on their crop.
A few years ago one farmer at avebury was charging £5 to see his 'ring' ;),though, the suspicion was that he'd made it himself.
I don't know how much but I think crop circle season brings a small boost to the local economy. The nearest microlight company does well and the local pubs are swelled by people with matted hair and children called 'leaf' and 'galaxy'.
Its hilarious to see people from all over the world standing in these alien crop circles, arms aloft, taking in their energy and power when all along it was probably made last night by ollie, stonk and 'ten gallon' alan on their way back from the waggon and horses.
