Wanted to remind folks that 72hours is just the start of preparing for disaster. With several bad storms lately, and the two earthquakes with the well televised results, I have been re-checking my preparedness supplies. I can comfortably go for about 12 days, and if I rationed I could go longer. This is assuming loss of municipal water. I am going to try to extend it out a bit more over the coming months. I look at 72hrs as the bare minimum, and if you had the bare minimum in Chile this weekend - you would be out of water right now.
