Many years ago an impressive wall appeared either side of an entrance near here, apparently leading nowhere except into a field. My parents named it Hadrian's Wall. Only later did it become clear that a house was being built, and speculation followed that the person living there should be called Adrian. So for no better reason the wall became known as Adrian's Wall!
Coming from Seaview direction there is a layby just beyond Adrian's Wall and the cache can be retrieved without crossing the road or even leaving the layby. It is now about 25 metres from its original location at the other end of the layby as it went missing from there twice.
