What is the reason you like bleach over a good hand pump water filter (MSR Water Works)?

If you are stocking up on food you should also think about a "disaster kitchen". A camp stove plus a supply of fuel for it. For example my stove, an MSR Whisperlite Internationale Multi Fuel Stove, used about 1.5 liters of kerosene a week. I was cooking two hot meals and a pot of coffee for 4 people each day. Kero sucks to burn, it is dirty and smokes like a Cuban. If you can get white gas do so, it burns clean enough to use inside, not that I would recommend that. A few easy to clean pots, plates and mugs. Something convenient to store your purified water in. Two big low tubs to do the dishes and laundry in. I will be glad to go on if asked, I lived "outside" for two years so I am pretty good at it.
