My DH spent 21 years in the AF. My DB is a Vietnam vet and said people spat on his unit when they all came through the airport when they came home and called the murderers! It makes him feel bad to think of it today. My DGS is in the AF presently. I am thankful for all the vets that have gone before us and for the ones presently serving to protect our Country. I just wish everyone in the Country was grateful for them... Things are changing...
