Book excerpt: The thin morning fog, hanging over the sage and bluestem, obscures the trucks and trailers around the pens at Peek Trap. The sun, edging above the horizon, draws the eye from modernity toward something more durable. A whinny in the distance sharpens your focus on a band of shadow cast by a low bluff. The first few horses run into the new light, and the rest of the remuda emerges, strung out along the base of the bluff, nine dozen geldings running parallel to the horizon a quarter mile out. Another day begins. A day that has endured over a century in character. Welcome to the Waggoner Ranch.
