Citing an open window on a cold March evening as the difference between life and death for a teen-age whose car had plunged over a cliff, leaving her hanging upside down in the wreckage, local residence Bobby Hull was heralded as a hero Tuesday night as he was conferred the Citizen Hero Award during the meeting of the DeKalb County Commission.“Bobby Hull is a true hero because God allowed him to make a decision to act on something that didn’t seem normal,” said DeKalb Fire Chief Donny Green in giving the award. “Without his action, it is most likely no one would have heard or saw Courtney’s car until it was too late.”The Courtney to whom the chief referred was 18-year-old Courtney Nichols whose was returning home on Cookeville Highway in the early evening hours of March 24.“As she was navigating a curve on the wet road, her Jeep Cherokee hydroplaned and went out of control and overturned before it came to rest upside down at the bottom of a steep ravine,” the chief revealed, noting her vehicle could not be seen from the highway.With the teen realizing her only hope was to sound her car horn, she began sounding it in hopes someone would hear it. Meanwhile, a distance away at their home on Blackberry Hill, the Hulls were cooking dinner and had opened the window for some ventilation.“He stood at the sink and heard the faint sound of a car horn,” the chief said, noting they continued preparing dinner but decided to go out on the porch as the sound persisted.
