Simply stated, hiking to the summit of Guadalupe Peak is mentally and emotionally the toughest hike I have ever done. And I’ve done a lot of hikes. Throughout most of our three thousand foot ascent, I’m feeling just one banana short of a bunch, an ant short of a picnic, one hump short of a camel. Y’know, terrified. Trudging up the sides of these cliffs, there is a tornado of, as my brother Laurence would call it, the squigglies, buzzing around inside my body. A symphony of jimjams, the dithers and shakes, the colleywobbles.
