Well we had no green tick, no "computer says yes" moment, no co-ords to check and no solution to this puzzle whatsoever. Cue the employment of our team's geographic research team unit last night. Within an hour we had come up with a likely spot where the cache could be hidden. After a good night's rest we hit the road and headed off for the pin pointed spot. No sooner had we parked the car we were enjoying an extremely well earned champagne moment . We had the cache to hand and we were enjoying a well deserved find as a result of great geographical research . We took the coin too. TFTC.
