Please be very careful, the A1 is a very busy dual carriageway, under absolutely no circumstances try to cross it on foot. The parking co-ordinates are by far the best way to approach this one. The co-ords won't take you to the exact location, but to prevent a human hedgehog situation (you never know, some people do take things a bit literally) they are close, you should get the idea of where the cache is before you reach GZ co-ords, if approaching from the parking recommendation.
With it being the Geoteens twelfth birthday, we thought we'd take the opportunity to expand on the previous Buckden Birthday and make this number two! Didn't quite get organised on time but thats when the idea for the cache materialised. Too small for a FTF reward, just the notoriety this time, happy hunting.
And finally.... you will probably require some assistance with retrieval, so go prepared, or be prepared to return equipped....
