i felt we had to go to old traditions, traditions of my hero, ernie pyle, the famous world war ii correspondent we as a nation are going to commit soldiers for 13 years, we doggone better be there to tell their stories day in and day out and you can't send them off and forget about it. i felt we needed to be there every day so that i could be there telling their stories, what they were enduring over long periods of time. >> woodruff: and your son said i'm coming with you, and you originally didn't think it was a great idea. >> no, no, not really. i mean, i was concerned because, you know, we've lost a lot of friends covering many different wars and this war as well, and i knew what the consequence of that could be. i mean, this is my son. but i started to realize that he was the same age as those young men and women who raised their hand and said, i will go to afghanistan, i will go to iraq to serve my nation, and this was his way to serve. he was bound and determined to do it, and that's what he did. you know, we are so close now because of this. we made it through it, and i really love my son
