We carried everything on our backs. We unrolled & recollection TP to save space kind of trips. Take 2 pair of underwear. You wear 1 and rinse the other out to dry as your walking to the next site. Averaged 9-14 miles a day depending on the terrain.
VERY different perspective of this country from that angle. Saw some utterly amazing things too. Grizzlies less than 10ft from us, snowball fights in June at the top of a mountain pass. Streams so cold they would take your breathe away when you touched the water. Elk, eagles, hearing wolves at night......just amazing.
Did the Cascades, Grand Tetons, Isle Royal, Glacier, Yosemite, to name a few. Have also done a few canoe trips like that where you packed everything and instead of walking we used canoes. Paddle to our site, camp for the night, then back to the canoes to go further downstream.
Those were great times.
