Etiquette Quiz in General geocaching topics Posted August 22, 2015 One of our most memorable swag items was a battery. We found it in a cache that was in like a weird cookie tin with kittens on it. The battery was memorable because it was the exact battery that we needed for our garage door opener - kind of like a short AA. We traded for it, and got many years use out of it. And it came out of a remote, rarely found cache with a ridiculous container. Don't you hate it when you replace yer watch battery every three years and they only sell yer size battery in packs of two?
