For me, PE was co-ed in grammar school (late 50's-early 60's). In junior high, we were segregated from the boys. Good thing, too, because we had to wear these horrible blue gym suits . We had to wear these through high school as well. I was in both Colorado and Alabama in high school. Two states, same gym suit. No wonder girls didn't want to play sports back then! Not that we could. This was way before Title IX.

Those were the days...
