Responding to the enduring lure of the West that captured his imagination as a child, Jerry Ellis decides to follow the trail of the Pony Express, a short-lived, hell-for-leather mail delivery service that lasted just one and a half years starting in 1860 but has marked itself in national memory ever since. Starting his journey in St. Joseph, Missouri, Ellis follows the Pony Express trail across Kansas, Nebraska, Colorado, Wyoming, Utah, and Nevada to the end of the line in San Francisco.

Ellis succeeds in completing his twenty-one-hundred-mile journey by foot, horseback, covered wagon, hitchhiking, and canoe. Open to what he finds, including his own frailties, Ellis reports with sympathy and humor on the strange variety of the modern West.
