>>You don’t think Dallas has a chance?<<
Dallas has probably the best chance. 2 major airports, a very well known high-tech corridor and already a very large Amazon distribution center.
By Dallas I mean the metroplex. Dallas itself is boring as sin. But Frisco and some other areas like that would be great homes.
If you include Alliance Airport there are 3. I agree that somewhere in the metroplex might snag HQ2, but many of us here in Plano and Frisco are tired of growth for growth's sake. What used to be nice quiet suburbs are becoming very busy and congested.
