I voted Dallas, but I live in the Fort Worth suburbs. I wouldn’t LIVE in Dallas, though I’ve worked there.
Tarrant county, which contains Fort Worth, was the ONLY major metropolitan area in the country to vote majority Republican in 2016.
I’m thinking the DFW area, as well. Affordable housing and no State income tax.
The Plano/Frisco area would be horrible traffic time to the DFW or Love airports.
Southlake would seem to me better located near DFW Airport and would also offer close access to Alliance Airport and Meachem in FW (which is planning on beginning commercial flights in a year or so).
