“How fabulous down was for those first minutes! Down, down, down I'd go until down too became impossible and punishing and so relentless that I'd pray for the trail to go back up. Going down, I realized was like taking hold of the loose strand of yarn on a sweater you'd just spent hours knitting and pulling it until the entire sweater unraveled into a pile of string. Hiking the PCT was the maddening effort of knitting that sweater and unraveling it over and over again. As if everything gained was inevitably lost.”
