Yup, done a lot of it here in Idaho's wilderness both elk hunting, flyfishingand shed hunting. Longest trip was 9 day elk hunt. We used horses on the 9 day hunt though! Longest backpack trip 5 days. Hvy packs, and Kodiak is right you really need to be geared up with the "right" stuff. to pull it off comfortably and safely. My trips have been into Hells Canyon, The Seven Devils and the Salmon River/ Frank Church wilderness all in Idaho.
