We just visited this godforsaken place today, when I returned and read about it here I wondered - what if anything has happened on the News story posted here? http://www.themodernantiquarian.com/post/23311
Not that I've heard of. There was talk of moving them to the Manor House Museum, but it seems to have gone a bit cold. I'll have a poke around and see if I can find any updates.
Yes the stones are in a poor state and seems to be unvisited apart from a few rock-art folks and people taking their dogs for a s***. As Stubob notes, I remember seeing bits of paint from the fence splattered on the rocks last time I was there too.
Get 'em shifted somewhere safe I reckon.
