Though I don't live in either Gainesville, I'll step in here and say that the northern most Gainseville is certainly the prettiest. I've always thought of Gainseville Georgia as the gateway between Atlanta and the N Georgia mtns.
A very nice town you have there in Gainesville, GA. I'd like to live there, someday. During my most recent visit, about 18 months ago, I enjoyed a nice dinner with my wife at Rudolph's.
Regards,
Sam
