What Can the Japanese Tsunami Teach Us About Prepping for Disasters and Emergencies?

Many of those that laugh at preppers are the same people that have health insurance, car insurance, home insurance, boat insurance, motorcycle insurance, disability insurance, travel insurance and business insurance.
But they won't lift a finger to get some "food insurance" for themselves and their families because that is what "preppers" and "conspiracy theorists" do.
Well, a whole lot of people in Japan wish that they had been "preppers" just about now.
