“Keep up the speed,” I tell myself. “Good, good, got this, uh-oh, soft dirt, yes?, no, oh no, going down!” And down I went, my right knee taking all my weight on a rock edge. Angry and a little embarrassed, I ignored the new wound, got back on Tall Boy and plowed the rest of the way up to the summit. Blood running down my leg, this was the moment my friend Joe, an emergency room doctor back home at a D.C. hospital, had been waiting for. Med kit in hand, he went into action, washing and treating my wounds. He seemed disappointed when he pronounced that I wouldn’t need stitches.
