Fun fact (or geeky fact, depending on your point of view) is that GSW is the airport code for Greater Southwest International Airport, the old Ft Worth airport that used to be there. Then DFW came along and now AA's training center is across the street from the old terminal. Part of the taxiway and run-up area of Runway 17 still exists at the northern end of Amon Carter Boulevard, on the north side of 183.
