We only use approximately 42 gallons of water per day, and that assumes we flush the toilet every 2 hours (we don't). If we switched to camp style dish-washing, laundry, and bathroom, we wouldn't need that much.
Since we have a well, and several backup ways to access it, we have a water supply, in addition to our 22 gallons of bottled water we have 2000 gallons of rain water and the supplies we need to make it potable.
We have a year's supply of most basic food staples, and are working on getting a year's supply of everything else. The least we have is 3 months for some items (not considering fresh perishable stuff).
Plenty left to do. We have always stocked up for emergencies, since we have power outages and tornadoes pretty often. It is hard to believe that there are people who do nothing to prepare for the chance of an emergency.
Did anyone see that woman in New York area after hurricane Sandy, standing on a street corner, yelling President Obama, we need help, we are dying out here? I don't know about you, but begging Zero for help, is not part of my preparedness plans.
