Sorry Freelancer , you won't be able to get that close, The Celtic Gypsy was lucky to get into the circle, normally only by special visits these days, The rope barrier is there to protect the stones from too much attention from visitors. As a child we were able to play on them, but I suspect that the protection of the stones is very important now. English Heritage( who look after the site) actually don't allow touching of the stones at all now, sadly
