I live in Jax, and while I haven't tried FWA yet (I need to), I do belong to two others. POW (I won a contest and thus, membership), and NFW (I think, North Florida Writers). I was pretty disappointed with both, as it seems neither have published authors, unless you count self published, but I was hoping to get some insight as far as queries and such, but they know about as much as I do.
In fact, I was going to hit the FWA conference in November (the one in Orlando), but I got talked into the Jacksonville POW writers' conference that's the same weekend. It was really cheap, and I was worried about spending so much money with the other one being at Disney, plus the fee is crazy high for the FWA one.
Anyway, now I wish I would have dropped the cash for that one (though I still have no idea if it'd be worth it), because the other one seems to be a bit of a bust. They moved it to a community college, and it's now free (because no one was joining, I think), and one of the contests they have is for a publishing contract, but when I looked up the publisher, it was a vanity press...
*sigh* I wish there were successful authors in my area. I'm desperate for guidance.
Maybe FWA is the answer.
