Given the popularity of park caches of late here is another. GPSr reception in the area is very poor so don't feel like a muggle if you use the clue.
The cache is a 200ml Sistema Box with small swaps BYO PEN
Keep a look out for muggles (real ones) at all times - they can come on foot, on bikes or in cars. You may have to pick your times and Geokids or a bottle of metho and a cleaning rag could be good decoys.
BBQs, Toilets and bins for Cito are also available.
GZ has wheel chair ramp access and if your the type of chair user who wheels down the street on your 2 back wheels your laughing. Small wheeled / power chair users may need an able helper should you bog as there is wood chips for the last few meters to GZ. The cache has hand access from a chair.
Please make sure the cache is returned to exactly the same spot. Twice I have found it in the wrong spot and in full view of small muggles.
