.............So, I'm thinking of a cache. It could be in a buried container on the corner of your yard, a storage facility, a boat, at a family or friends home (you have indicated this in your responses). Something that you could "bury" for ten years and know it was there if you needed it.
Here's a link that talks a little about caches. There are others that speak about how to build caches (mostly smaller pvc type).

I'm going to use a couple of 55 gallon containers. They should hold enough supplies.
