When they arrive in Montana, they first are in Livingston. The next stop is in Deer Lodge, which seems logical enough because it's about 145 miles to the west following I-90. But the next place they show up is Laurel (by the waterslide), which doubles back THROUGH Livingston and then another 100 miles east on I-90. The last stop, where they are ultimately found (Rollins) is on the west side of Flathead Lake, 425 miles doubling back. The fact is, Livingston is correct, and Rollins is correct, but they didn't stop in Laurel, or Deer Lodge necessarily. Their path was from Livingston to Belgrade, then just past Deer Lodge they got off I-90 and worked their way to Salmon Lake before eventually arriving in Rollins.
