Seriously women didnt get emancipated as early as you think. Des Moines High Schools had zero, nada, no high school girls bball until about 1970 iirc. Not even 6-girl bball. Title IX wasnt passed until 1972 and I just looked up an article that said in 1970 20% of high school girl athletes were in Iowa even though the state had only 1% of the population. But that has all changed.
I graduated from Des Moines Lincoln in 1970 and there was no girls bball, volleyball, track and field, softball , hardly anything. Amazing how long women and girls have been held back in many areas, but not surprising.
