Secretary of Defense Robert Gates arrived in South Korea Friday. He's there nearly two months after North Korea launched an attack on Yeonpyeong Island.

But there's at least one group of men that military recruiters are staying away from, North Korean defectors. From Seoul, Jason Strother has the story.
