There are 3 major pecan-producing states in the US: New Mexico, Texas, and Georgia. New Mexican cooking tends to have a distinct Mexican slant; I've never come across any great Pecan pies there, although they may just be hidden away somewhere. But Texas has a long, proud relationship with the Pecan (it is our state tree, after all), and Georgia is the number one producer of Pecans and is well known for its pies in general.
It seems reasonable, then, to search for the best Pecan Pie in those two states. Personally, I'm cheering for Texas (state pride 'n' all), but I feel that I can't rule out Georgia as a possible dwelling place for the King of Pecan Pies. So, where are the best Pecan Pies in Georgia? Hopefully I'll be able to go try them some time, but right now it's kind of academic unless there's a clear-cut winner (in which case maybe they'll ship me a whole pie), and that seems very unlikely!
If you're not from Georgia, but feel that I have erred in narrowing the contest down to Texas and Georgia, by all means tell me about it. There are bakeries and restaurants in Louisianna and Mississippi that claim "the best pecan pie in the south", so maybe I'm way off base.
