I also asked the lady in the garage who looked at me like you do to to the slightly bewildered. I followed her instructions to take the next right and to look for it in the large gorse infested moorland behind the garage. I walked to the end of the road and then found my way into the gorseland. After much searching I found the stones at the high gorse just to the left of the garage. I then saw the mechanics watching me with much amusment, after shaking my fist at them I had a look at the site, I can’t add any more than the other two postees except that if you park just where you turn right then walk carefully scanning the hedge on the right, about twenty metres down you will see a vague path which leads straight to the stones about twenty five metres away, saving you a very painful trip.
