Texas is similar to Indiana in that there are large areas outside the
jurisdiction of any city. The entirety of Texas is divided into
counties. Texas counties have no townships; towns can incorporate
under the general law, and cities can achieve home-rule.

Someone mentioned the Montana portion of Yellowstone National Park.
As of 1999, that area is under the legal jurisdiction of Gallatin and
Park counties. (separately) So that is no longer among the county-
equivalents of the USA.

And Roanoke city, VA, is bordered by Salem city as well as Roanoke
county.
