I hear you about the heat, but reality was that I used more water in the winter than I did in the summer. I attribute that to the much larger caloric intake in the winter. 4000+ a day requires some cooking and cleaning. And the body requires water to process that much food.
Wilderness living is hard. I did do it. For over a year. I don't do it, today, unless required. ;)

The people are suffering needlessly because the socialists in control have removed the profit incentive;if the price gougers could make a profit they would be carrying everything needed as fast as possible.
This current Government IS the problem.
I spent a month on a NOLS course in Wyoming. Of course, in the Winds, as the instructors told us, there are two seasons - winter and the 4th of July. And that year, it snowed on the 4th of July. But yeah, wilderness living is hard. Especially back then, when NOLS had you pack out the last four days without food (something they no longer do). But it was a good lesson - for short-term survival of a few days, food is not critical.
