My girlfriend and I reorganized a large closet in our home into a pantry/supply closet. Now we call it "The Bunker." When we counted all the stuff we had, we've got at least 10 days worth of water (And a water purification system of filters and tablets) and three weeks worth of food. After we up the water supply to 14 days, I'll pretty happy with what we've got for our situation. And most of the foodstuffs are what we normally eat anyway. With the emergency ration bars and MRE's we probably actually have 4 weeks of food.
And I've got quite a few bullets and TP!
