When Susan Terrio found out on Arlington National Cemetery’s social media that a Vietnam War 50th Anniversary tour would be held on Sep. 27, 2024, she immediately booked a flight from her hometown in Eden Prairie, Minnesota, to Washington, D.C. She invited her father, Jack Terrio, a Vietnam veteran, to go with her. He was initially hesitant, as he has experienced post-traumatic stress disorder (PTSD) and was not sure he wanted to revisit his memories of the war.
