Might you include Dallas-Ft Worth in the Arklatex?

Can Dallas call itself a citizen of the Arklatex?

Is Dallas-Ft Worth part of the Arklatex, a region where 3 states meet? At 2.5 hours driving time, they are not too far from Shreveport, which is definitely part of the Arklatex. Yet traditionally they are not proximate enough to qualify. Shreveport and Dallas share a line of latitude, approx 32 degrees north, but it is not relevant to the definition of Arklatex.
