For this Wherigo Geocache you will use a Reverse Geocache Box (as part of the Wherigo Cartridge) to find ground zero. The Box will give you how far away you are from GZ in metres but no other information until you are really close.
This Wherigo Geocache can be started from anywhere in the world; however it is strongly recommened that you are in the vicinity of the Whangarei Town Basin.
The cartridge needed to play/find can be downloaded from Wherigo or the Wherigo Foundation.
This is my first Wherigo Geocache with a couple others in the planning stage. I hope you enjoy it.
