"tom k, you misread what the guy said, he didn't say he could go for 14 days with 10 pounds base weight, he said with a 10 pound pack." See the difference?"
Nor did I say that is what he said, Harald. Actually, what he said is: "Our adventurer sets out. He (being a man I will NOT speak for women) has a ten pound backpack. His full skin out weight is twenty pounds." So, his pack ends up being 20 pounds, including somewhere in the neighborhood of 6 pounds of consumables, assuming clothing worn weighing in the neighborhood of 4 pounds, more if his clothing worn is less. Do you see the difference? He mentioned no number of days, but followed up with: "To the UL'ers: You have ten pounds on your back, how many days can you stay out with it?" It was that comment to which I originally responded with MY 14 DAY answer based on my 11 pound base weight, an insignificant difference of one pound to which he objected. For a strict apples to apples comparison, based on a 20 pound total weight for both of us, I should have responded 5 plus/6 days, because my clothing worn is 3.5 pounds, my food per day weighs 19 ounces, and I do not cook if I want to travel really light or am going to be in bear country, therefore I need no fuel. Where the 14 day number came from is what I have figured to be the maximum I can comfortably carry in my OHM, extrapolated with complete confidence from field experience on 11 day trips with an OHM plus non UL field experience on trips ranging up to 17 days unsupported. The 14 day full skin out weight would be: clothing worn = 3.5#; base weight stripped down to 9# for a trip of this length, because we're no longer talking hypothetically(i.e. no camera, stove, fuel, etc); food = 16.5# @ 20 oz/day(add 1 oz of coconut oil for extra calories due to trip length) for 13 days plus 4 oz for lunch on final day. The grand total is 29#. I do not count water because it varies all over the place. Suffice it to say for a long trip like this I would choose a route that offered easy access to water for the first few days, and would carry a max of 1# for a max total of 30#. So, for 9-10 pounds more than our apples to apples 20 pount total weight, I can stay out 14 days. It would be interesting to know how long a BCer could stay out by foraging and remaining at a 20 pound total weight; I suspect the answer would vary all over the map, depending on skill level and availability of forage. However, I doubt it would be 14 days, simply because it is very hard to obtain sufficient calories by foraging alone, unless one is hunting, and even then it is a challenge. Fish do not supply a lot of calories, as I learned the hard way on a 16 day trip long ago, nor do berries, roots, salad greens, etc.
"You most certainly cannot go anywhere with an 11 pound pack for 14 days as an UL backpacker."
True enough. That figured referred to base weight, as did his hypothetical scenario with a 10 pound base weight and 20 pound total weight. Hopefully I clarified that above, although I would have thought it was pretty obvious. At any rate, I guess I should have spelled it out.
"It's important to actually read what people say when responding"
I think I read what he said pretty carefully. However, I should have made the original response an apples to apples response.
"for a 14 day trip,...... it weighs roughly 14x 2 pounds (food/fuel/etc consumed a day) plus your baseweight plus water."
You are way off the mark here, Harald, based on your faulty assumption of 2 pounds per day for my consumables, as I explained above. You would do well in future not to make such assumptions about other hiker's food requirements and cook/no cook styles.
In closing, I would like to indulge in a little thread drift regarding posting etiquette. My original post, whatever you want to say about the contents, was civil in tone. The response it received from Mr Vinzant was not, to say the least, and your response, Harald, was, as so often seems to be the case with you, downright condescending, as if you were trying to explain something simple to an especially slow child. In the event, you were a bit off the mark yourself. Neither attitude is conducive to a productive discussion. The actual content of your posts get lost when the recipient either responds in kind of simply walks away, leaving the discussion either unfinished or spiraling downward into a flame war. When I post, I am totally willing to listen to any and all criticisms of what I post, in fact I welcome them, and feel it is my right to reciprocate. Civilly. I am all in favor of discussion, debate, even vigorous argument, but when the posts turn ad hominum or condecending I object. That happens all too often, IMO, and has ended many a good discussion prematurely, to the detriment of the community.
