I had the same question, I have to admit.
No, they’re not a high school football team, though we were sitting as close to the sidelines as we would at a high school game, as evidenced in this photo of Norm in the stands (complete with his new Flash hoodie).
Apparently, American football is fairly popular – the stands were full of fans from Flash’s city of La Courneuve (a suburb of Paris) and Amiens, whose team is the Spartiates (yes, the Spartans).
Norm and I happily cheered for Flash – whose colors are black and gold, like the Saints, and also like the Spartans of Salmen High School, where I taught for many years. (It seems we were predestined to be Flash fans!)
Unfortunately, Flash lost in the last few seconds of the game: twenty-one to fourteen. We had the best time nevertheless! There is nothing like American football to make the homeless feel more at home in a foreign land.
