Before we could begin to know whether cityhood makes sense, we have to know the area(s) that might be considered to create a new city. So, folks, "who are we?"
While you're at it, why not share your reasoning? Is it a strong community of interest? A strong mixture of commercial/industrial and residential property in a contiguous and reasonably shaped area? What makes sense about the boundaries you chose?
Ask yourself: "Who are we?"
