Echoing Kelsey's sentiment, I also grew up in Atlanta, lived in Home Park, and while I wouldn't say that I felt unsafe while I lived there, I now live in an actually safe place. It's unbelievably different. People actual walk around. I see women walking alone. I don't see sketchy people, I don't have to lock my doors (my house in Home Park actually had two deadbolted doors before you could get inside). The red line prior to five points is well known to be the safest line, but people still harass you on it. I don't know when you lived in Atlanta, and I was only taking Marta the last three or four years that I lived there, but it's definitely not good/safe public transit.
