If you have already found GC5DDAA Squelch (Canterbury) then you are half way there.....on the edge of a small quiet reserve on an otherwise busy road. A couple of seats....and a quiet gap in the trees beside the holding tank; you can lean on the tank and look nonchalant as you scan for the cache...should be in plain view around your feet - watch where you are stepping!
Just a random cache in a random spot....some might remember being here previously searching out a pandas tap....
Use stealth; it can get busy at certain times as there is a daycare down the back of the adjacent lane-way.
