Since I am renting our home, modification is out of the question. All available conventional storage space is already taken, pretty much up to the ceiling, so no more shelves can be mounted with aesthetic impact that the wife won't tolerate.

As I have said in previous threads, I have too much stuff in my house and need to get rid of some of it. Were it my own house, I would simply open a hole in the floor and start excavating. Dry earth is a great place to store food. I am pretty sure the water table under my house is quite a ways down.

I just got an idea for a new thread.
