One of my good friends in high school lived in Lackawanna. His dad was a veterinarian and ran his practice over there, too. I also briefly had a job in the area in college, working at Pure Ice of the South, Inc.
I love the area. Sure, it needs a bit of work and would benefit from an influx of new residents, but it definitely has the bare bones for being an up and coming neighborhood.
Jacksonville has so many of the great little "lost" neighborhoods that you'd never really know about - that's one thing I love about this website. And that's one of the things I love about mandatory busing and going to school on the Northside. I got to see places I never would've known existed.
