I happened to be exploring around Glen Eden and Kelston today....and I came across some possible Hiding places !
After parking at the end of a no exit street....I continued walking past a Pump Station ..
At the bottom of the slight hill I found a suitable place to hide a tube in...and you won't be overlooked by houses !
No need to bush bash . Very close to pathway . Not in a tree.....Not Ground Level
May be approached from either Aronui Terrace or Kiernan Place ...There is a walkway between the two streets ...
