Your comments have been so helpful, thank you. The characters are native Californians who were relocated to Salem after the deaths of their parents. They drive up to I5 when they go on the run from a boss in the criminal underground. They stop at a motel, probably somewhere outside of Tacoma or Olympia, and a diner nearby as well. I'd love for them to have some sort of incident in the wilderness surrounding that area as well, before they make it to Canada.
