...a spouse who thinks they are crazy? LOL!
Much less so after Hurricane Sandy. We were the only house in the neighborhood with running water for a week after the storm. While most have generators, we all have deep wells and nobody else had their pump wired to the generator circuit.
In spite of the spousal mockery, I had saved a variety of containers that I gave away to neighbors who hadn't thought about water beyond bottles of mineral water from the supermarket, and I put a a food-grade hose on the spigot in front of the house so neighbors could fill up as they needed.
It never got so bad here that I had to break out any serious stores, but I know that the Mrs. appreciated that our lifestyle never really missed a beat and that we could help others.
