Something about the drive to the Palmer house from Odessa Texas that bothers me is, they presumably did it in one night. They are shown refueling but arrive in the same cloths all night scenes. Carrie had a packed bag so if they stopped, surely she would have showered and changed clothes. Its about a 3 day drive from Odessa to Seattle. This leads me to believe Lynch purposely left that plot hole in the show as a clue.
