First Edition Of " Backpacking One Step At A Time " by Harvey Manning copyright 1972, and " Freedom Of The Hills " Third Edition " 1974 which I read and reread over and over. Learned more my early climbing ,knot etc. straight out of that book,, then bought the gear and just " Did It ". Self Taught On Repelling, Ice Axe Arrest, etc. and practiced,,,, lots,,,. Nice to reread these today with all the cool old " Retro Gear ",, stoves,tents, packs,etc.... I would still advice any outdoor hiker/climber to get a copy of each of these fine books. ( First Edition if you can find one! )
