CJ-Curry: Maintenance person has come to check it out, and sent me photos.
The place where I originally put the cache is now gone, and is unlikely to be replaced in a way that houses a cache (at least, not for a good few years). There's nowhere else in the park where my maintenance person can place the cache in a way that keeps the spirit of the listing.
So, after nearly nine years, it's time to let this one go.
Thanks to the nearly 250 accounts that found this cache over the years, and to my maintenance person for keeping it alive for so long.
