On a more serious note. To keep rain off of my patio, we are hooking up a few big drums to some new gutters to collect rain water from the Garage & House. Which could be used in a stay at home kinda emergency after being filtered.
Plus we have a good supply of medical supplies & canned food. I joke about learning from Jericho the TV show, but do feel that the writers weren't to far from the mark with regards to how society would lower it's standards to survive.
