Rock HQ, above, is, as the name suggests, built on a rock. Its also underneath a huge rock, we have our own climbing wall. Then up on the Bonsai Mountain are various slabs and monoliths of 700million year old rocks that from time to time move and make life interesting. The drive way often has a new small boulder on it. The cars in the turning circle have been moved forward a tad as the Berners cavorting across the mountainside sends small but windscreen shattering stones cascading down its flanks. There is a very impressive standing stone (centre of pic above) that keeps watch over the smallholding.
