Don't forget the rivalry between these two academies!!
Grew up within 10 miles of one (CG), had a neighbor who attended the other, and never knew nor cared that there was a rivalry.
It seems I vaguely remember Otto Graham being the coach at Coast Guard for a while back in 70s or 80s, so at least I knew they had a team.
The “little ARMY/NAVY game” was Norwich University vs USCGA.
