My son (18) and I (49) wish to thru-hike AT in 2007 and are starting to prepare now. Other than a few 20 mile day hikes without packs, we're complete novices and have much to learn before we make the attempt. Strapped on a 6 lb. 6 oz. pack loaded to a total 30 lbs. at REI and felt a bit wobbly in the knees. Don't think I'd enjoy (or survive) with that much weight. Really, really motivated to try AT but think we have to go Ultralight. I know there are some long stretches on AT between resupply points. Three questions: (1) Since we will both be carrying packs, what is the recommended minimum capacity for each of our packs? I actually bought the 6 lb. 6 oz. pack but now am thinking I should return it. But, I'm worried about carrying packs too small for food and water over longer stretches. (2) Over the trails longer stretches, how much weight should be allowed for food and water per person? (3) Any great web sites for Ultralighters?
Thanks for any help you can provide two future thru-hikers.
