I visited the site on 22 December 2006. It may be quite difficult to find if driving on the busy A45 dual carriageway and the following may help. If coming from the Rugby direction take the second left after the Fosse Way roundabout near Stretton on Dunsmore - this is Freeboard Lane and you can park immediately on the right. Cross the cariageways and take the signed public footpath to the left of the houses opposite - the site is easily visible a few yards to the left. If you miss Freeboard lane there is a lay-by a few hundred yards down the road.
If coming from the Coventry direction I suggest locating the site as above and trying to park outsie the houses described, or else go to the Fosse Wat roundabout and come back towards Rugby.
In any event, a pleasant site and well screened from the main road.
Visited Greycroft on 22 July 2006. In fact we just had a sight of it from the adjoining Seascale golf course. The ninth tee is the nearest point of the course to the stone circle, visible around a hundred yards away but not directly accessible because of wire boundary fences, and somewhat overgrown. There is no other obvious viewpoint from elsewhere on the golf course. I only had time to take a couple of photographs before disappearing down the nionth hole, so it was hard to form any detailed impressions.
[visited 30 July 2006] The grass verge had recently been cut, including right to the edge of the stone. It sits in the middle of a lengthy strip of grass between the lay by and the main road, opposite a public path leading alongside a wood and flanked by numerous wild flowers. Despite the fast traffic nearby the area around the stone seemed quite restful. The nail is still embedded in the stone but looks relatively recent in origin. I took a number of pictures as previously there were only two.
