ceesmond: After a recent spate of DNFs, I had a look at GZ yesterday, and decided to archive this geocache listing. GZ isn't what it used to be, and it's only a matter of time before the widening of the road will compromise it further. Besides, the puzzle has run its course. Most avid puzzle cachers in the area have already found it.
So yes, the cache was missing. There was no container at GZ, and that will remain so.
The last three cachers that posted a DNF are welcome to log a find. They put in the work and were at GZ, and should have found it if it had been there. Who am I to deprive them of a second (and in one case third) chance?
Thanks everyone for finding this one. It was the first What3Words geocache puzzle in this area; more have been created since.
