All the towns in Wyandotte County are now in the Unified Government. That may be what you are confusing things with. They still are their own entitities though. Piper, Edwardsville, Turner, all the rest as well as KCK. Technically KCK doesn't have a mayor anymore but it is still a city. They just combined all of those city governments into a county one and let that do the whole deal but they didnt consolidate the different towns.
