We had these things on the rooftops of certain buildings all over town: https://www.youtube.com/watch?v=7bPAjQYCAUw One late afternoon, they all went off. It was not a test. Tests were always just one siren at a time. This was all of them. The sound is unmistakable. You can feel the vibration in your bones inside your house. We all knew we were to run for cover - but we all also if knew if a nuke was inbound, there would be no survivors. People did not take cover. They came out on their porches and stood around staring at the neighbors. It was like, oh well, I guess the party is over now. 15 minutes to the end of the world. --------------------
