Students at Lake Central High School in Indiana get a personal experience in U.S. history by participating in a project teacher Tom Clark started 27 years ago. Year after year, Clark's students have archived documents and other items from Indiana's war veterans and their families. The project often brings powerful person-to-person contact with military veterans or their survivors that goes beyond numbers and dates. "This textbook is going to say 58,142 died" in Vietnam, Clark tells his students of American casualties. "Is that meaningful? No. That's why I do this."
