I had worked through these puzzles over the course of several weeks with a view to finding them on a visit to St. Albans at the end of August, I managed to puzzle out six in the series myself and had help with the last two from Alistair and my Dad. In the end we didn't have time that trip, so we decided to have a look for them today on the way elsewhere.
Had to have a little nudge from the CO to finish this one off, but got the co-ords in the end.
We tried finding this earlier in the day but were beset by a loud yapping dog the other side of the fence. We left and returned later on. Doggy had been called in for his tea and so Alistair and I were able to carry out a finger-tip search of the GZ. I started one end, and he started the other. We had almost met in the middle when Alistair found it, sneakily hidden.
Have a fave point for the brainpower required.
