Scan the Midtown skyline and you'll see a crane or two. And if developers actually follow through on what they've pitched to neighborhood groups and journalists, they'll start popping up along Juniper Street. And on Ponce de Leon Avenue. And then who knows where else. These towering beasts, which for the last four years have been a rare sight in a metro region that for decades was about nothing but construction, have slowly been flowing back to Atlanta, into the dense urban core, where they should have been years ago. Unlike developers' previous fascination with condos, this go-round they're erecting apartments, where young people and empty nesters can snag a home high above Atlanta, overlooking a city that, one hopes, keeps growing steadily. If there wasn't a feeling that's the case, we wouldn't be seeing them.
