Trying to locate a Vietnam War veteran from Detroit - he was my mother's penpal while she was in high school via a school-arranged program. All we know is his name is Don, he is from Detroit, likely born between 1944-47. We also know that he did make it back to Michigan. I have a few photos of him if anyone has any ideas how I might track him down? My mother would love to reach out to him, if he was open to it. Thank you!
