I'll admit this up front, I recorded this on an Ipad on the way home the week before the Inauguration, 2017, so it's in the future tense. Our President has been in office for about two weeks now and I just found this audio Snippet on my Google drive.
I should know better when I hear cannon fire at the work place.. I left my job on the 13th of Jan that night and heard the steady syncopation of BOOM BOOM BOOM BOOM and it took me a few minutes to realize what I was listening to. The Old Guard Saluting Battery, practicing for their big moment of giving the new President a 21 gun salute. Someone has to do this.. and if they are going to do it, they are going to do it right. I've seen this many times, and they are a good outfit-- thoroughly professional. In the short gloomy dusk of a Friday evening in January, it completely mystified me for a moment. Only in Washington!
