Haha...I'm sorry it's just funny to hear the words "MARTA" and "smart move" in the same sentence. It's quite a surprise that MARTA was so effective for a murderer, yet when I took it to Hartsfield Airport from North Springs (about a 25 minute drive) it took 2 hours!
If I were taking Marta from north springs to the airport, I'd give it an hour for good measure. Bet Nichols made it from downtown to Lenox in 10-15 minutes flat.
