>>1294394Not that guy but it depends. MARTA is only really useful for getting you into town from the suburbs, otherwise it's pretty shit tier.
But Atlanta is very bikeable within the beltline (except for nigger zones like Bankhead and English Avenue). You'll be fine getting around if you work near the city center where most jobs are to be had.
If you work in a suburb, chances are you will need a car, and your commute will be miserable.
