Trudging through the snowy hills, the travelers stop at the mouth of a narrow pass and stare at the campsite below. A long line of people in heavy jackets lead to a collection of tents that are surrounded by a white wall. It takes Dawn a minute to realize that the barrier is really a circle of snow-covered wagons, which have been connected to each other by metal plates fitted into two grooves. Bike-powered generators are scattered about and the caravan members take turns maintaining the lights and heaters. Livestock can be heard from far away, but the animals are nowhere to be seen. As they walk down the steep incline leading to the valley, Kara points at a series of barns that look to be collapsible. Guards patrol the top of the wall, each one given a single car to stand atop instead of trying to leap over the gaps. Dawn frowns when a man whistles and shakes his gun in their direction, but the threatening gesture is quickly turned into a silent order to get in the back of the line. Not wanting to cause any trouble, the pair do as they are told and join the huddled figures who are hoping to be accepted.
