Changing of the Guard at the Tomb of The Unknown @ Arlington

For those that are not familiar with the changing of the guard. The 3rd US Army Infantry maintains vigil 24-7. The sentinel paces 21 steps alongside the tomb, pauses 21 seconds, then returns. The changing of the guard takes place every hour. As you watch listen to the background and you will hear a funeral that is in progress. We were there for 3 or 4 hours and I heard at least 5 funerals going on. It is definitely a special place that you must see.
