How do people commute from Marietta to Atlanta?

The drive from Marietta into Atlanta runs mainly along I-75, with I-575 feeding into it from some parts of town. Timing is shaped heavily by rush hour more than by raw distance, and Marietta's own downtown square area is compact enough that the local portion of the trip is short. Ask Joel about realistic commute expectations from a specific Marietta address rather than a general citywide answer.
