(NECN) There are more than 21 million veterans living in the United States. For some of those servicemen and women, the biggest challenge wasn't serving their country. It was making the transition back to civilian life.
Retired Marine Sergeant Brendan O'Toole of Alexandria, Va. just completed a year-long road trip to raise awareness about their plight. He ran 3,600 miles through 21 states, from Oceanside, Calif. to Portland, Maine.
"You start to get real tired out there. We had terrible weather, tornadoes, sandstorms, blizzards, dogs chasing us," said O'Toole. "It's been rough."
