Can confirm, the South does have sweet tea. It's good n stuff. To answer your question, yeah, I'd totally be down for visiting BrickFair, AL as I currently live the closest, but probably not this year. Also, I'm planning on moving, so we'll see what happens, lol.
As far as we are currently aware, it's only for the contest. I would certainly hope that it gets a widespread release, though. I would buy that in a heartbeat.
