I've been to the Rollrights today for the first time in a couple of years, and was surprised to see the surrounding area layout VASTLY improved.
The fence by the stones has been removed and there's loads of room to walk back and take a photo of the full ring http://www.suaveharv.com/rollrights.jpg
Also, there's a pathway to the Whispering Knights so you don't have to walk the risky route along the road.
How long has it been like this? It's much better. Sorry if this is old news, but it's good news.
