Wonderful and amazing. Thanks for posting.
I was a grounds keeper at Arlington National Cemetery for two summers when I was in college. I mowed the grass and trimmed hedges and tress etc. It was a very humbling experience. I saw hundreds of funerals. We were required to stop whatever we were doing and wait for a funeral service to end. Several members of my family are buried at Arlington. My father is buried there. He served in WW II and Korea. I visit regularly. I’ve been on almost every square inch of the grounds.
This is a link to a youtube video about the Old Guard. The Oldest Active Regiment in the U.S. Army. As a military brat I spent a good deal of time around Ft. Myer when I was a kid and Arlington Cemetery.
