Every weekday when the clock strikes 5pm (or rather, 1700 because the Army is on 24 hour time) everyone within earshot stops where they are, faces towards the flag, and listens to this bugle call (there's a surprise at 24 seconds!):
When we were living in the hotel right across the field from the flag we would try and come out and listen as often as possible. Hearing the cannon go BOOM is so loud and powerful and makes me very proud.
Yesterday I was running errands at the PX and as I exited the music started. I loved seeing everyone stop, turn, and if in uniform, salute. For just a minute everyone is united in purpose and intent.
Makes me feel so patriotic :)
