I don't know that my old school [[St. Marys of Redford) ever had a rivalry that could be considered 'best in the state', but I know they had some good ones in the old Catholic League [[back when it had MANY teams, including Servite, St Ambrose, Bishop Gallagher, Shrine, Holy Redeemer, ...). St. Ambrose was one of the big football powerhouses back in the day, I'm sure they had a big rivalry or two. Dearborn High and Dearborn Edsel Ford has always been huge.

Funny thing with St Marys - we didn't have our own football field [[other than our 2 gyms we had no real sports facilities at the school grounds), and for a while we used McKenzie's field for our 'home' games - I think it was called Hammersburg Field or something like that. Dad took me to a few games there as a youngster.
