Everyone should be prepared. Like in the olden days. Those where the times when their was no government to come and save you. You where on your own :)
People have become to complacent. Nobody wants to see another Katrina happen, or Sandy. Just takes a little thought and preparation. If you can't get everything, I'm sure one of your neighbors can help. Just like you could help them with certain things. This is just like they did years ago, before all the amenities. Everyone banded together to help each other.
