I voted for Houston. I agree that someone also needs to develop KATL, since it is a Major US airport. FSDT has developed KLAX, KORD and KJFK. KATL should be placed of their short list of future developments. FYI, FlyTampa is presently developing Toronto. It looks like that development is well under way. FSX users definitely have a bright future of enjoyment ahead of us. Cheers!
