Ft Oglethorpe is probably one of the fastest growing areas in Walker Co. The main drag between there and Ringgold is Battlefield Parkway/2A and it's BOOMING! The changes in the last few years are quite amazing. There are the typical big box stores, movies, diners, strip malls, a high school, plant nurseries, grocers, etc... I cannot imagine what kind of business they need down there so I can't help you on that one. But I would say that area has the highest retail business of the few cities I am familiar with.
Chickamauga is of course my favorite - and other's as well

Quaint downtown that DOES need someone new with a brilliant idea. I think they have done some good things down there lately and need some more good people to keep the ball rolling.
