Henry Gomez, aka eaglephin as he is known in these parts, has started his evaluation of the Marlins fan demographics. Reading the series is well worth your time, the first part was released today.
Henry is a very good writer and his analysis is normally spot on. And it is quite possible, you may even learn something you didn't already know. I know I did.
I can't recommend his work highly enough. So give it a look see. (Yes, I lived in Louisiana at one point in my life.)
