Autumn Sang was at a mobbed grocery store in Tualatin, Oregon, on Friday stocking up for the coming storm for herself and her neighbor, who is disabled and doesn't have a car.
Sang said she had never seen the store so crowded. She grew up in southern Oregon, where snow is more common, and wasn't fazed by the forecast.
"I love it. I'm excited about it," she said of the snow. "I think that Portlanders, most of them are city people and they come from a lot of different places, so they're not so used to it. It's like, 'Use your brain! If you don't have to go out, don't go out.'"
