That is great.
I actually enjoy that part of watching a movie on a military base. That is all I have to say about that.
Back in 1982, a buddy and I went into town (Blytheville AR) to see the movie Poltergeist. The movie begins with a scene as someone (Craig T. Neslon??) sleeps in front of the TV right at sign off time. The National Anthem comes on
and my buddy and I snap to attention. We got plenty of cat calls for that.
