Final answer:
Texarkana, a city that straddles the border of Arkansas and Texas, is located in Miller County on the Arkansas side.
Explanation:
The city of Texarkana is uniquely located in two states, which are Arkansas and Texas. Specifically in Arkansas, Texarkana is situated within Miller County. This is a distinctive feature as not many cities are split across two states and still function as one urban area. Texarkana serves as a prime example of cross-state municipal collaboration and is also noteworthy for the sharing of state and local resources and services between the two Texarkanas.
