CHARLOTTE, N.C. -- The gas shortage is so severe that people are sleeping in their cars.

Thursday night, dozens of drivers snoozed in their cars yards from gas pumps as stations across the Charlotte area waited for gas shipments.

“I was told last night between 11 and 12; then I was told this morning,” said Kelly Davis, who sat in her car at the Citgo on Lawyers Road.

Davis is stuck in Charlotte. She came to the Queen City for a vacation and can't get back to her home in Pennsylvania. She was supposed to return Thursday.

Rather than driving around, she said she gave up and is just waiting with her tank sitting on "E."

Davis’ was one of 25 cars that parked at the Citgo overnight. Some of them are there by the driver's own choice, others stuck because they've run out of gas and they had to be pushed to the pump.

Dennis Rice and Patricia Morel said they planned to stay at the gas station for the long haul.

“My car is on empty – I can't even leave,” Rice said.

The two have been sitting in line since Thursday morning.

“We've already spent overnight, and have been here since 9:30 Thursday morning, so we're just waiting for gas,” Rice said.

And after glimmers of hope gas might come, late Friday afternoon the gas still hadn’t arrived.

Davis said the whole experience turned her sour on Charlotte.

“Here I am down here vacationing. (This) ruined it,” she said.

Many of those who could leave the Citgo eventually did Friday, but some are still waiting in line.
