A QEF PnG in an urban environment.
Once at GZ you will soon know what you are looking for.
The nearby property is occupied by retirees and you know how nosey they can be so use discretion and don't compromise the cache.
The hint should help minimise the search time, so you shouldn't be lurking suspiciously for too long.
The cache is a magnetic camouflaged mint tin with a write in the rain log sheet in a small plastic bag.
