Much the same here. We have communities and some incorporated cities with their own City Councils, Police Departments, Garbage Department, right next to each other but with their own names, but they are all in Sacramento County..I think you need to define town! If it's a half a mile away then it's part of your city.
Guess it's like Orlando area with Kissimmee, Windermere, etc.
We don't do that here in my province. the entire city of 800,500 is all called Winnipeg. We don't have individual towns in a metro area. there is no "town line" between neighbourhoods. But I understand that bigger cities do.
When I think of towns I think of small prairie towns of 500 people with 50 miles between them - not big urban centres.
