Katherine is a ranger at the Arlington House located on the grounds of Arlington Cemetery. We were there on a busy Sunday and it was her last tour of the day. She was outstanding. Katherine is another example of how your experience at a National Park Service site can be enriched by an energetic, knowledgeable and enthusiastic (and funny) guide. She went well beyond what was expected and provided a memorable tour that enabled us to see much more than anticipated. The folks who staff the Park Service work with too few resources, too many people and work, often for years, with only the promise of another season. And most of them are, like Katherine, stellar. Thanks for the great time at Arlington House.
