Located just across the Potomac in Arlington, VA, this "moving", "inspirational" site is the "sacred ground" in which at least one veteran from every American war is buried – more than 350,000 people in all; whether contemplating JFK's eternal flame, witnessing the "changing of the guard at the Tomb of the Unknowns", trekking along the "beautiful" "walkways and hidden paths" or taking in an "authentic view of 19th-century life" at the Custis-Lee Mansion, it's a "historically rich", "emotional experience" that "takes your breath away."
