Several years ago my wife and I traveled from our home in New Hampshire to visit a Civil War battlefield in Pennsylvania; not just a battlefield, but the Gettysburg battlefield, a mammoth site where an equally mammoth strife between two sides each one populated with citizens of these same United States.
It was our only Civil War and it was fought and ended with the hope that families of these United States would never again raise their hands in anger against a fellow citizen of this country. Suffice to say that hope has held to this day and I personally believe that it is due to the unspoken message that this venue implants in each visitor who is fortunate enough to view.
