i think the thing to do is have las vegas the city as the primary article and include in that all urbanized adjacent areas that are not part of another city this covers the strip the airport palms and most big off strip casinos and all the county islands btw county islands are not an indication that a place is not part of the community but an indication that the annexation is corrupt i think that would cover things well and address the fact that henderson and nlv are not quite as las vegas as the strip fwiw it seems that las vegas is unusual for a primary city of a metro area to not be surrounded on all sides by suburbs this is probably why other cities haven't had this argument talk to me
