Letter box hybrid for those that don't know contains a stamp (in
this case two stamps) and a log book, it may also contain some
small swaps. The idea is that you bring along your stamp and stamp
the cache log book, then use the cache stamp to stamp your log book
(if you have one). The idea is to collect stamps from as many
letter caches as you can. If you are not collecting stamps you can
treat this as a normal cache, by signing the log book and making
swaps as usual.
PLEASE DO NOT REMOVE THE STAMPS
FROM THIS CACHE.
This is a very exposed area so extreme stealth will be
necessary.
GPS coverage was pretty good at time of placement so once at GZ
the letter box should be very obvious.
While signing the log have a look at the windows above you, in the
2010 floods the water was half way up them
