A 78-year-old driver ran off the highway and was trapped and injured in her overturned car for nearly two days before a trooper saw skid marks and found her.

Betty McCord was hospitalized in fair condition after being pulled from the wreckage off State Highway 9.

"I was hanging upside down in a car for two days; you talk about some kind of horrible," McCord said Monday in a phone interview from her hospital bed. "I couldn't get out of the car. There was no way out and believe me I would have found it if there was."

McCord, who had injuries to her knees, ankles and head, said she doesn't know how or why she ran off the road.

She had called her granddaughter while on the way to visit Friday evening, but was reported missing by relatives after she failed to show up, said Capt. Chris West, an Oklahoma Highway Patrol spokesman. West said a trooper noticed skid marks Sunday and walked through some brush to find her car.

"She couldn't get out," West said. "She had a head wound, but she was coherent and able to talk."
