As for the school itself it was part of a now deserted town called Popash here in Florida in the late 19th and early 20th centuries, it sort of faded away after a railway was built but bypassed it in favor of Zolfo Springs. There's not much left of the town, save for an abandoned church, its graveyard and some houses. That's sort of the brief rundown of it, I'm sure you can find better info on it elsewhere.
I'd love to go back and get photos but I live in Orlando and I haven't been down that way for oh, about 4 years. But if any of you others here are in Florida, I'd really recommend going and checking out what's left of Popash.
