I ran across this article on another newsgroup
which dealt with some of the conspiracy
theorists in the US that are burying guns and
ammunition in case they need to shoot someone
someday.

It is an interesting read, and covers many things
I hadn't thought about if, for instance, I wanted to
bury something valuable somewhere.....
