I can't remember taking PE in elementary school, but I do remember that the receiver for the college football team (my elementary school was on the college campus) taught boy's PE. That was in Louisiana.

Moved to Michigan. Jr & Sr. High (two years) - had separate PE classes. Our uniforms were knit things - shorts & t-shirt combined with a zipper, blue bottoms, blue and white stripes on top. I think the designer had in mind the top would blouse over and it would look like we were wearing blue shorts with a blue & white T-shirt. Yeah, right. Seems the zipper was supposed to go up the back, but as they fitted so badly, we wore them with the zipper in the front. We also had swim classes, and the school supplied the suits - which were color coded according to size.

Moved to Arizona

Seems one year I had dance all year for PE. Or as an elective class. But I was also in Band. My senior year no PE and was in band. I think with that school district if you were in band you didn't take PE. Considering band practice was just before lunch we would sometimes march through lunch too.
