I've watched high school football all across the southeast up to Northern VA, and in terms of community/fan support, Florida is dead last. I'm guessing that the large transient population that doesn't have community ties is part of the reason. The high school back in my old podunk Virginia hometown with a population of around 4.5K will draw 3K or more for home games, and most of those fans have been supporting the school for decades. Most of my Florida game attendance has been in Volusia, Orange, Brevard, Broward, Palm Beach counties and here with the Treasure Coast schools from Sebastian River to South Fork. With few exceptions over the years, the crowds have been mostly students and parents/relatives of players, cheerleaders and band members.
