I used to live in PTC. Very nice place for a family, but not if you are single. Some people prefer farther out where you can get more land for less money; I preferred having neighbors who I saw and knew by name; being able to ride a bike with my kids without fear of being run over by an idiot Atlanta driver; good schools; being able to make my way home without driving if I had too many to drink.
I used to live closer to Atlanta Speedway before moving to PTC. I hated it. Many of the other south side towns in Atlanta are "slam click" communities. People drive their cars into their garages, close the doors, and you don't see them again until the next morning. No sidewalks for the kids. Kids are discouraged from playing outside. I asked for speed bumps in my neighborhood to cut down on the speeders and the town said they couldn't due to law suits from people who get their cars damaged. Well, if the car was damaged, they probably drove too fast.
No kidding on this next one. Schools don't have cross walks. The town does not want kids walking or riding bikes to schools as they then could be held liable. So if you live across the street from the school you have to drive you kid to school. This was the final straw that caused us to move to PTC.
