Ponka&thePonklets: I have visited and the cache has indeed disappeared. When placed this cache, this was a lovely and well maintained corner of the park. Over the last few years it has become overgrown with nettles in the sunmer and is obviously a bit of a teenage drinking corner with all sorts of nasty rubbish there today The experience is not what it used to be.
I am therefore archiving this cache, rather than replacing.
