Yipes! I think you are right! I researched your figures (calories per ounce) and checked your math, and by golly, you are right! Darn it! Well, there's youthful enthusiasm for ya, running again into that brick wall of reality. I do weigh 225 pounds, so maybe that 15 pounds of food would be enough for a week, or less. I had thought that because my foods would be in "staple" form, that I would get more calories per pound out of them. Where do I come up with these ideas? So I guess the usual rule of thumb for weight of food per day per person applies even to me?? Is that what you're saying? I hate that! Well thank you for the reality check. It's probably better to know this stuff before I head out. Perhaps I ought to think this through a little. <applause> I'm glad I ran this idea by some experienced backpackers. Maybe I'll hang out on the forum for a while, make a spreadsheet, do some calculations, before heading off on my grand adventure. I imagined myself the day after eating the quantity of berries you mentioned, and it wasn't a pretty picture! That must be why wild bears sh!t in the woods. They can't wait! hahaha. Looks like I have LOTS to learn yet.
