Do you ever wonder how people can write new books about history? Shouldn’t it never change because it’s all in the past? The truth is anything but, and no one can explain that better than today’s guest, Dennis Frye. Having been involved in everything from giving tours to leading nationally important preservation and battlefield protection organizations, few people know Civil War History like Dennis. And in his new book, Antietam Shadows, he makes the case that history should never lie dormant, it always needs to be re-examined. Join as Nick and Dennis talk about Dennis’ new book, highlights from his career in preservation, and more on this week’s PreserveCast.
