National Park Service Ranger Troy Harman joins the Strategy Bridge Podcast to talk about the role of the location of water, roads, and rail in the decision making during the Gettysburg campaign. We also talk about how symbolism built into the design of the park shapes views of the battle. Harman has served as a ranger at Gettysburg National Military Park since 1989 and he is the author of "All Roads Led to Gettysburg: A New Look at the Civil War's Pivotal Campaign."
