Hay fever, different crops, tragedy, emigration and yet more argument. Yes, the 2006 crop circle season is now under way... or is it? The rumours spreading around the wacky crop-circle world of Wiltshire are that there might not be as many of the mysterious formations this year as in previous summers.While some people who claim to make the crop circles say they are hanging up their planks and ropes to have time out, others in the furtive world of the circlemakers pledge that this year will be the biggest yet.And then, of course, there are the crop-circle devotees. They scoff at such planks-of-wood nonsense and say the more other-worldly circle- makers are sure to carry on.One thing is certain, the possibility that there will be fewer, or even no crop circles this year, has sent the close-knit croppie community into a geometric vortex.It was prompted by probably the most famous circlemaker in Wiltshire, Matthew Williams, announcing he would be taking a year off because hay fever, probably sparked by the increase in oil seed rape fields, was getting the better of him.Mr Williams, still the only person in the world to be found guilty of crop circle criminal damage, said: "I'll not be out this year, it really is getting too bad. After a night in the fields, it takes me at least a day to recover."He, and other crop circlemakers were also stunned by the death of one of their number, Paul Obee, who was found dead in a car at Erlestoke, near Devizes, last month.
