More than 400 Navajo are believed to have aided the war effort as code talkers. Less than 50 are estimated to be alive today when their critical contribution to victory can finally be recognized. How lucky for me to have stumbled on these men on a sunny Sunday in Old Town Albuquerque. Not every day you get to meet true American heroes, awarded the Congressional Medal.
