Sustaining audience for a graduated HS cohort?
You probably know of places where interscholastic football has fandom well beyond the family of players. Are there any where you think enough interest has transferred from the institution(s) to cohorts of players to organize them economically for post-graduate play, assuming they weren't good enough for college or fully pro varsity to fund? What I have in mind is some town in which one or two graduating classes from one or two or three schools could do it.
The only examples I can think of were the Sayreville (NJ) Bombers, who reorganized into what's now the A7FL, and a partial example in Saskatchewan who became a university team and apparently didn't have the interest or wherewithal to make it an independent club. I'm sure there were plenty of examples from before there was enough money in football to cream the crop, but I'm looking for contemporary examples, on the model of people who perform for small remuneration in community theater and music, but may have known each other initially from local schools.
