Food has got be be by far the heaviest item we carry. If you really want to stay UL, consider placing a wilderness cache as I did this summer. But you can't always hit civilization every 5 days, so the cache has to be in the wild, and in my case, at a location below timberline. Could give you the link, but it is easier just to go to page 2 of this forum and look at the thread entitled, "Hanging bear canisters." It is all on there, except the Opsac clips that are available from Amazon, and noted on yet another recent thread. I only clipped the outer Opsacs.
It was fun locating a good site to hang the Ursack where I could readily find it but nobody would run across it. And it was a good pretrek warmup to spend a day packing in and hanging just 5 days of food and the cache stuff. Your back will thank you.
This is something that has always intrigued me, but I know next to nothing about. Could someone give some pointers on how caching should be done? I'd love to read an article about this.
