They Traveled From South Korea. They Got Stranded Near Buffalo.

A day earlier, he had grown concerned after receiving messages from friends alerting him to the coming storm. On Friday, the van ride was slippery and windy, and the passengers had become anxious, he said.

Then, after hours of watching the weather deteriorate outside the van’s windows, they ended up stranded near the Campagna house, Mr. Choi said.

The Campagnas, well aware of the dangers the storm presented, immediately invited the travelers in, “knowing, as a Buffalonian, this is on another level, the Darth Vader of storms,” Mr. Campagna said.

The visitors — seven women and three men — filled the three-bedroom house, sleeping on couches, sleeping bags, an air mattress and in the home’s guest bedroom. The other travelers included parents with their daughter, an Indiana college student, and two college-age friends from Seoul. Three of them spoke English proficiently.

They spent the weekend swapping stories, watching the Buffalo Bills defeat the Chicago Bears on Christmas Eve and sharing delicious Korean home-cooked meals prepared by the guests, like jeyuk bokkeum, a spicy stir-fried pork dish, and dakdori tang, a chicken stew laced with fiery red pepper. To the surprise and glee of the Korean guests, Mr. Campagna and his wife, who are both fans of Korean food, had all the necessary condiments on hand: mirin, soy sauce, Korean red pepper paste, sesame oil and chili flakes. There was also kimchi and a rice cooker.
