Don Ledford leads a full life. At 59, he’s five years shy of retiring from his career as a Public Affairs Officer, but he has no intention of slowing down. He spends his spare time training for ultra marathons and hiking 300-mile backcountry trails for weeks on end. “In my mind, I’m 30,” he says. But even Don did not know what his life was missing until he held his grandson for the first time.
