I wouldn't think I have ever went more than a few hours without drinking some kind of liquid and liquid falls under etc.. I have never been lost in the desert so yeah.
I was really hoping someone would come in trying to tell us "Oh, at least a week"
Huntsville is a nice place. One of the better places to live and work in the States. I was born there, but grew up about 50 miles away so was still there a lot.
I have never been ran over on foot, but hit on a motorcycle and in a few car crashes. I was never at fault, and never seriously hurt. Very lucky a couple times, though.
