The thing about hiking the Pacific Crest Trail, the thing that was so profound to me that summer—and yet also, like most things, so very simple—was how few choices I had and how often I had to do the thing I least wanted to do. How there was no escape or denial. No numbing it down with a martini or covering it up with a roll in the hay. As I clung to the chaparral that day, attempting to patch up my bleeding finger, terrified by every sound that the bull was coming back, I considered my options. There were only two and they were essentially the same. I could go back in the direction I had come from, or I could go forward in the direction I intended to go.
