Who ya gonna call when the next big earthquake/volcano/tsunami/fire etc. disrupts your life? We all know that FEMA will leap to action and promptly fall to their face in a near comatose state. The Red Cross will try and be there with food, water and blankets and there will hopefully be a few law dogs and fire fighters mobilized. The national guard will do what they can with the stripped down, over burdened and underfunded resources that they have, but when the crap really hits the turboprop you had better be ready to buckle up and weather the storm alone, because there is a good chance that for several hours to several months thats the only help that will be coming.
Be aware, be prepared and start deciding which neighbors you will eat first.
