Marvin Grimm, who treated wounded Marines and served with them in combat as a Navy hospital corpsman during the Vietnam War, can speak from personal experience about the meaning of Memorial Day. "Despite all of the tragedies that occurred, I take a lot of pride in the lives that I did save," he said. Grimm, who earned two Purple Heart medals in the process, will give the keynote remarks Monday at the annual Bulloch County Memorial Day Remembrance hosted by American Legion Dexter Allen Post 90 in the Emma Kelly Theater.
