Hello Robert,
Thought you might be dropping in at some point on this one. You may be right, although I would hope that even at your most critical (or should that be cynical

) you'd concede that this is a particularly beautiful "circle", with much thought and effort put into its construction (by whoever or whatever).
This latest one, photographed today, and contained in the link below, is rather less impressive, I think. It resembles a dragonfly. But as it's also of a creature (the previous one was a jellyfish - probably), and was discovered within days of this other one, and in Wiltshire - not a million miles from Oxfordshire - it may be that there is a theme developing here.
As a small-time "croppie" myself (as in interested in looking at them, and in the phenomena generally, definitely NOT making them, because it is vandalism, actually, however pretty they may be) I'm sorry to say that the crop circle "fanatic" quoted in the article doesn't really help the cause by lapsing into 2012-speak (see Slate article above).
Judge for yourself from the photo. But whatever did it, I'd have to say, not his best work. I mean, it's okay, but certainly not a patch on the jellyfish (if that's what it was).
