We live in Bowling Green, KY. I know of one Church in Nashville, but we have two young children and it is hard for us to make it that far early in the morning.
Unfortunately it looks as though Nashville is the closest. I would urge you to continue your studies and visit as you are able. Perhaps if you can visit once or twice you can then have an email correspondance with the priest that could help you in your inquiry of Orthodoxy. If we can help, we will be happy to assist. Seek and ye shall find!
