I'm a bit limited as far as location due to my pup, but it's looking more like IB will be the place over Academy Advantage. Driving from Tennessee myself, and I'll definitely hop in the Facebook group as soon as I'm not on a work computer.
As far as Centers go, I think my top picks (if they were somehow available) would be ZSE or ZDV, with probably Boston, DC, and maybe Chicago up there. I haven't found much info on the Chicago center, but it's the closest to home for me.
