A Letter from Iraq: Sgt Christopher Pasternak

Today is Friday, the day when we check in with the members of the 36-43rd Company of the New Hampshire National Guard.

They're stationed in Iraq, doing duty guarding a detention center just outside of Baghdad.

We don't want to waste too much time, because Sgt Christopher Pasternak has a lot of stories to tell NHPR's Mark Bevis.

Pasternak is the company's lead medic.
