My mom lives in Stockbridge, just outside of Atlanta, and my brother works landscaping in and around Atlanta.
She said, from what she had gathered, that they weren't calling for things to get bad until like noon/1ish, but it started getting bad around 10 or so. And that some school chose not to just close for the day, instead they decided to close early, forcing more traffic because people were getting out of work early to pick up kids, or leave work.
I don't know, she lives really close to I-75, she said my brother didn't work yesterday or two, and my youngest brother's high school closed yesterday and today.
It's crazy, I can't believe how bad the interstates look on the news!
