Hmmmm...

I hadn't thought about the salt. I don't know how quickly your body looses salt (perhaps some of the medical types can help us out here), or even how much you need to replenish. Given that they make salt tablets its obviously important. That being said, I don't recall ever reading about putting salt in your survival kit(?).

Other than that, I can only say I think that you're right and that you make a good point. I guess I'd get me some salt packets in that condiment bag. It would be nice to have a rule of thumb as to how much you should have with a gallon of water. I might mix a rudimentary saline solution if I knew.

Of course if I were already in the 7/11 and someone reminded me about this (I freely admit I wouldn't have thought of it), I would probably go pick up a bottle of Gatorade and look at the "nutritional facts" to see how much sodium it contained per bottle. From there I'd do a little math and plan for the right amount of salt.
