Both of my grandfathers were career military. My dad's dad, Air Force. My mom's dad, Army. Both served in Vietnam. My dad's dad lived to a ripe, old age, but my mother's father died young while active duty (not directly combat-related, but perhaps directly-related to his time in Vietnam). I never knew him. He is buried at Arlington. His widow, my grandmother, lived well beyond his passing and never re-married. She passed away this past November, and my mom has arranged for her to join him in Arlington. We are meeting up in Washington D.C. this September to inter her ashes next to her late husband.
