Oh, I remember the rules. There were even curfews for the dorms. And I can’t remember males EVER being allowed in female living quarters, only the common areas.
“Chapel” is still mandatory, at least for the first 2 year, and was changed to “forum” when I was attending. It was more of a speaking venue for guest speakers, after singing a few hymns and praying.
I think it was only one female dorm that had upper classmen coeds. It was around 79 or 80. Not in the Freshman dorms. A long gone era....
