One month after his 45th birthday, Marc Mayfield became a long-haul truck driver, something he'd always wanted to do. Away from home for weeks at a time, he crisscrossed America in 18-wheelers. Drove into sunsets and, often, nonstop through the night. Learned firsthand that truckers paid by the mile are shortchanged with every paycheck, that the federal Hours of Service are as unrealistic as they are dangerous, that every day meant threats to his truck, his cargoes, and his life. But he loved the solitude of a truck cab and traveled more than a million accident-free miles. Along the way, he all but destroyed his marriage. Then he met someone he didn't know he was looking for: himself.
