I've been walking a rescue dog for the last couple of months since the passing of my wife, for a local kennels. I do it for exercise, and to keep her father/my father-in-law company. Eric is a Great Dane - very big but fortunately very placid, and this is one of a set of caches that follow one of the main walks we do around Treeton Dyke.
The third cache on the walk and a slight diversion to a dead-end gate. Once you have found the cache backtrack slightly and go through/around the larger green gate.
