I was away in Miami for a street survival instructor course, (law enforcement). That days class didn't start till the afternoon for some night training. I woke up in my hotel room, turned on the TV just in time to see the 2nd plane hit. Watched all morning, then went to class. Was surprised they didn't just cancel the training.
Finally came home a week later. My wife had put our flags out, the big one, a bunch of little ones, kinda like she does for flag day, Memorial Day etc etc. And she's not even American, a German living here with me for 30+ years. Loves the US and more patriotic than most US citizens. Never Forget.
