Let's define robust, shall we? I've never known four people who could agree on a happy definition in this conext. Anything truely robust isn't going to be beaten by just throwing a dictonary at it, but anything that good, most people won't remember.

In all honesty, there is something we are forgetting here. Make notorized copies. Put them in a sealed envelope. Mail them to Aunt Susie May in Ohio or some other relative who is a couple hundred miles away. If you need them, she'll likely have them.

I'm holding that kind of thing for several of my friends at my folks, on the theory that if my parent's house isn't going to flood even if the ice caps melt over night and the firesafe should stand up to anything that else that can take out the house.
