All boys were required to be in the ROTC. Reserve Officer Training Corps. There were four companies. I was Captain of company D in my senior year.
We had Swords as part of our dress uniforms.
When I was in the US Army, I could have gone to officer training, but I would have had to stay additional time.
I went to the square dance club, and learned how to square dance. My wife and I went to square dances later on.
