robnzh: Time for this to go.
Dampness has been a recurring problem, even after trying allegedly waterproof containers, and I don't live nearby any more.
For personal reasons I won't be able to get to GZ for some time, if anyone can pick up the cache and use it or dispose of it as they see fit I would be grateful as I don't want to leave geotrash, especially in this environment.
Thanks to all the finders.
