quote: Ray Jardine (author of a lightweight hiking guide) has hiked the AT and the PCT with a 8.5 pound base pack weight, with no problems. His gear was not expensive either, mostly because he can sew well.
Nothing personal, but I would not want to hike any trail of any length the way Ray Jardine did it. Not that he is wrong in doing so, but I would rather use a tent, not a tarp, for instance. I usually carry about 45 pounds on a 3 day hike, and I don't bring anything that I'm not willing to carry. My pack, a Dana Designs Terraplane, weighs 8 pounds empty - but it feels so sweet with 45 that I bring the sorts of things that make the trip more fun for me. That is what it comes down to, fun.
