Just a reminder - You will want 1-2 gallons of water per person per day for a minimum of 14 days. I highly recommend 2 gallons or more.
Remember, you can use the PETE containers used for juices at the supermarket. Just wash/rinse and refill with tap water. These are easy to obtain, store, move, refill, use.
A survivor of Hurricane Katrina reports that when disaster strikes, the first thing you think about is water. (That would be right after - is my family ok?)
You will die without water before you will die without food. In addition to drinking, think about the water required to prepare certain food stuffs. This isn't just about brushing your teeth. A bath every third day is recommended.
Good luck! Keep up the good work.
