How to Get Around
Atlanta has a comprehensive roadway network. Traffic can be very bad at some times.
MARTA operates heavy rail and bus service in Atlanta. The service is reliable if not extensive. Route finding services are available on Google Transit, and they just introduced a real-time information portal.
Cycling for transportation requires some level of courage (for the drivers) and endurance (for the hills). The rewards are there, too. Ask Greg or these guys for advice.
