I lived on PCB around five years ago. I know Comics Emporium (on HWY 231, on the north side of PC proper) has tables, but don't know if there is any historical action. They carry some 40k and not much else minis-wise.

It's a bit of a drive (though a scenic one) west to The Book and Game Emporium in Oceanside (though their site says it's Fort Walton Beach). Take the 30-A coast road til it hooks back into 98.
BGA has had gaming, and used to have some pretty cool stuff, though in the latter respect, they are a shadow of their former self.

TBS Comics in FWB has tables, and GW stuff, but I don't know much else about their goings-on.

I know of nothing else, but something could have sprung up since then, I suppose. Aside from Pensacola or Jacksonville, I can't say I'm optimistic. Hopefully, someone will be along with a fresher perspective.
