In sometimes frigid Bangor, Maine, three senior citizens have welcomed home or bid farewell to more than 800,000 American troops.
Join us as Mike Cuthbert talks to one of those greeters, Joan Gaudet, and her son, Aron, who directed and edited "The Way We Get By" - the award-winning documentary about the greeters and the work they do.
Aron saw his mother's life - which he has said "had slowed to a crawl" - transformed by her newfound passion.
Listen to find out how the three greeters changed their own lives for the better while setting out to make the world a better place.
