According to Doctor Internet, the Concordia College that Joerger matriculated from is in Moorhead, Minnesota. I know that these conference realignments are getting out of hand, but that's still a hell of a drive.
And yeah, I'm aware that HBCU doesn't mean exclusively Black. Hell, there's an HBCU somewhere in West Virginia that's, like, ninety-something percent white; most of the residents weren't aware that it was an HBCU. But most Historically Black colleges have at least been situated in places where there have, historically, been Black people.
