Not sure if the "slam" comment was directed at me specifically, but that wasn't the intent of my comment.

What I was trying to get at was that food isn't necessarily so important, since most of us carry around spare calories...is it going to be comfortable and fun, no.

Let me illustrate what I see as the problem that's being overlooked:

1 gallon of water weighs 8.35 lbs

The min amount that I normally see mentioned to keep the human body functioning every day is 1 qt or 2.08 lbs (approx), so for 16 days at 1 qt you'll be needing 33.4 lbs of water...not so bad. But wait, that's just to keep the body alive, so if you're going to be exerting yourself (sweating) maybe you'll need more water...say 1 gal. So now for 16 days you'll be looking at 133.6 lbs of just water.

And if you're looking at 35 days of walking:

1 qt/day=73.1 lbs, 1 gal/day=292.25 lbs

Would you be able to source some water enroute? Probably, but I see water as the main issue for surviving this scenario not food. Would the food be wonderful at making things better, absolutely!

The human body is capable of fantastic feats, as history shows us that's absolutely true. However, how many more common examples are there from when things didn't work out so well? I'm pretty sure those numbers would dwarf the success/survival examples throughout history.

And nowdays peoples idea of hardship, really isn't.

So, overall I think this scenario looks bleak for most folks. Would there be stories of incredible survival against the odds, undoubtedly...but they'll be the exception not the rule.

My 2 cents worth...
