About Sons and Daughters In Touch For the past 18 years, Sons and Daughters In Touch (www.sdit.org) has worked to locate, unite and provide support to the now-grown children of American servicemen who made the ultimate sacrifice in the Vietnam War. In that time, more than 3,000 members have contacted veterans who served with their fathers, visited the Vietnam Veterans Memorial and shared their life experiences with others. Today, SDIT members take considerable pride in knowing that the loss of their fathers was not in vain.
