How did you access it? From the north, via the farm? Approaching from the south there are parallel fences which I took (from a distance) to be a special concessionary path - I therefore didn't go to ask at the farm, having only about an hour left at the end of the day.
However the gap between the fences is filled with stones etc, so ended up having to negotiate a very high barbed wire fence. Consequently poor vibe, not helped by overgrown, rubbish-strewn surroundings - it has certainly deteriorated since Greywether's wonderful images. I then saw the farmer approaching and thought I'd be off rather than get in another argument. No doubt I would have felt differently with easier access.
The farmer did say hello SC and I spoke to him the other week as well, decent bloke who knows his prehistory, every now and again the farmer does cut down the overgrowth when time allows. We approached from the north east via a couple of rusty gates. Ages ago the Mad Man, Smith and me removed the rubbish tip from the circle area.
