There's a "living in Atlanta" thread somewhere that has some good info for you. I just bought in Fayetteville off Redwine Road.

Schools were huge deal for us too, Fayette county schools are good.

I met plenty of sim instructors that lived on North side and made the drive work. Didn't sound too fun to me. Woodstock looked nice and I think the drive is ok (for North side), though the braves are building a stadium up that way.

Good luck
