THE CACHE IS NOT AT THE LISTED COORDINATES but you can park nearby.
The inspiration for this set of puzzles came from my attempts to solve the nearby But is it Art??. Any resemblance is therefore entirely deliberate ... and probably misleading.
Solve the puzzle to enjoy a walk and some pleasant views in the Essex countryside. You are looking for a clip-lock box which might hold a few small swaps.
Congratulations to Mr Crow/gillywig/Kitty!! for the FTF.
