Well I went to West Kennett Longbarrow today looking for the circle
There was a couple asleep on the top of the barrow, so i woke them up and asked them if they knew of a crop circle near by

but they didn't so the bloke phoned his mate to see if he could find it. Then another couple turned up looking for it, they spoke Esperanto

Then some Americans also turned up looking for it.

The woman in the shop at Avebury had told them it was between Silbury hill and the Longbarrow but it wasn't.
So Dan I am sorry to say I failed in my reporting of it
I took some pics on my phone and will load them up later on.
