When we as homeowners or renters plan for disaster we can't afford to plan for the easy. Planning for the small disaster will not protect your family in a major disaster; but planning for the big one (your local big one) will protect you from the small ones. Having seven days of food and water will help get you through a hurricane landfall, a tornado strike on your community or the big quake we look at on the west coast. It will also help you during a 1 day power outage.
Just do a little everyday. Plan, store, think about how you will react. But above all PLAN FOR THE BIG ONE
