With no buses running at 5 a.m., Jefferson said she walked over a bridge until she got a ride from a stranger and then caught a cab to arrive at her job at the gas station/convenience store in Fairfield at 6 a.m., her usual start time.
"The snow was like beating me up in my face, like I'm going to war with the snow," Jefferson said. "I had to just troop it out."
Jefferson figured she'd be able to get a bus home after work.
"Don't let this day be like I'm not going to make it work," she said. "Sometimes you have to sacrifice. Also pray."
