" I'm not so sure. Having done 16 days at 1.5 lbs/day,"
here's the scoop, we're not hiking in washington, so there's no "off budget" weight. it ALL seems to be there when you pick up the pack.
thusly, even the sacred cheap rum's weight has to be accounted for. at Paul's low caloric and admirably in-shape situation, i'm not seeing any room for drink. just ... nothing.
my god man ... NOTHING ??? you go out there for days at a time, to watch the sun set, to rest along ridge tops and count eagles, to camp by rivers flowing, and with nothing worth drinking ? that's Un-civilized, that's what it is. i suppose the occasional torp weighs less, but this is BPL, and here is a good spot to find journeyman level drinkers of good stuff.
just a sociable use curve is going to nip ya thru 3 or 4oz a day. so 2oz/day at a functional minimum. if only to keep from getting a sore throat, eh.
got to think'n on Bob's comment that bear cans don;t hold quite enough for what they are, and yes, they seem to fill up too fast. peter recently gnawed thru a large bear-vault in a week, and was eating not all that prosperously.
so last night on the drive home, we got to pondering that my packing was not optimal. now suspect that since granola is a major component of my outdoor food intake, one might be well served by perhaps Not bagging the granola, but tossing it in last, like spreading sand on dry laid bricks. a LOT of granola might be able to ride along between all the less efficient packaging. since it's roughly 1/2 a pound of it every morning, removing it's packed volume could (we don;t know yet) extend the range of the bear can several more days.
i also made several other errors in bearcan packing. ie : we eat a 3oz foil packed slab of spam every day, and for some anal reason feel the need to pack these 3 or 4 to a ziplock. that's foolish from the the volume standpoint. might do better letting them float in my free-range granola (you read it here first), and reap the lost volume of the ziplock nooks and crannies.
bear can food is not like stuff sack food, in that if you don't muck about with the contents, stuff sacks pound down in few days to a more efficient shape and volume. in practice it worked out to roughly "if starting with 6 full sacks, by day 2, i'll eat and compress my way down to 5." thusly, we've been letting that 6th sack ride external the first few days, which they're going to be miserable anyway, and that lets us skate by with a slightly smaller pack.
might add that since i started toting the bear can, i dislike it quite a bit less. the annoyance of it's shape is to some extent countered by it being just the most handy place to sit.
sleds : a pulk lets you drag so much more stuff so much more easily.. it made a criminal out of a formerly decent backpacker.
food, fuel, extra clothing, even Camp Shoes ! ohh goodness, just toss it in the duffel, it almost won't matter.
i wish i was younger, could put all this good thoughts to better use, and didn't have to do laundry today.
