If you lived or worked near downtown Dallas, then Love Field was convenient. For everyone else that was closer to DFW, then that was probably more convenient (and the shiny new thing at the time). So you're superimposing that everyone didn't like the new airport, when it was just those with a vested interest in their nearby airport not wanting to drive a little further to the new one, when they might have been happier overall with more flight choices and less traffic in the vicinity of DFW in the mid-1970s.
Anyway, so about those Abandoned Runways Turned Into Roads...which is the actual discussion topic and title, and totally not about conjecture, hearsay, and anecdotes of past and present airport facilities.
