A simple little multi cache located near one of Marlborough's pioneering wineries.
Due to a conflict in coordinates with another nearby cache, I have decided to make this one a simple multi in order to offset the cache. At the listed coordinates you will find an engraved wooden sign. On this sign is a date (year only) which for the purposes of this cache I will call 'abcd'.
The cache can be found at S41 30.ABC E173 48.DEF where:
A = d-a
B = c
C = b-(2a)
D = b+c-d
E = b-a
F = d-a
Checksum: A+B+C+D+E+F=45
The cache is a 200ml Sistema container containing a cache note and at time of listing, a smiley-face token for swaps. BYOP.
