In the aftermat of the Florida hurricanes last year, you might have noticed the fedgov "revising" the recommended 3-day store of food and water to 10-14 days. IMHO, If you live with in 100 miles of the east or gulf coasts or in a major earthquake zone, you should consider 30 day's supply of essentials.

Also as stated elsewhere by TeacherRO, survival is a team sport. In the areas of NO where the surviving community members banded together, they kept the looters at bay and saved numerous neighbors.
