No, go back a few more years to the mid-late '80's - before Curtis bought the station from Durham Life. The Durham news bureau was in Brightleaf Square, the Capitol office was in the Legislative Building (not far fetched, because North Carolina News Network and WUNC-FM still maintain bureaus in the Legislative Building today.) And yes, there was a WPTF traffic plane ... before Metro even came to town. They used to show it off every year at the state fair. Remember Captain John Hoffman?
