"Read the survey, it's not just oil/gas companies - it's Fortune 500 companies in TX."

I guess I was not sure of the point you were trying to make? Take ExxonMobil for instance, their HQs are in Irving but most all of their R&D is here in Houston.

Not taking sides here - it was interesting to read the various companies in Houston, D, FW, Irving, Grapevine, S.A, etc

I think we are discussing financial impact of these cities. I haven't done the research, nor fully understand what factors constitute an "influential" city.

Regardless, TX has the most fortune 500 companies of any state.
