There was an old shelter near where I grew up. It was fenced in, but we dug underneath it. The place had the big drums of drinking water (WAY beyond shelf life), broken radio peices, and a rack of overcoats and CD helmets. We each took an overcoat & helmet. They were horrible, musty things, but we were kids....and the shelter was LONG since abandoned. I recently drove by it, its since ben razed & had houses built over it.
