"I came to love, really love, road marching. It's called a suck or a haze at West Point, but I think the cadets aren't being fair to it. There's something wonderful about being in a column of marching people: the gravel popping under soles, the leather flexing in boots, the kind of saddle-top sounds as the ruck (what a backpack gets called in the Army) frames settle. Occasionally someone, out of sheer misery, sighing Oooh, or just blowing out air, which in the general silence is like a whale breaching and then slipping back under the surface. You can watch a leaf float down from a tree or stare at the guy's rifle in front of you. The boiling of life down to its basic questions: Can you do this? Can you hang with the rest of us? Those questions don't get asked much, in the civilian world."
