Marta is the bus and rail service in Atlanta, Georgia. While I did not take a bus (or the streetcars that traveled along some parts of downtown) I did use it to get from the airport to downtown round trip and what a bargain it is! Taxi service from the airport to downtown is a fixed fee, as in many other cities, of about $32.00. A ticket on Marta for two was $7.00. It takes about half an hour from the airport to downtown and once you climb out from the underground you find your way to where you need to be.
The one station we popped in and out of was underground but many stops are above ground platforms. It seemed especially daunting – and deep – going down so I whipped out my phone and took this photo. Mind you, this was after we were about a third of the way down!
