 PLOT: The Hills travel to Montana where Peggy attempts to make  amends with her estranged rancher mother; in Season 2, Ep. 14 ("I  Remember Mono"), Peggy & Hank attend the same school in Arlen and  Peggys Mother is clearly seen looking like Peggy. In "A River Runs  Through It" Peggys Mother chastises Peggy for leaving the ranch  (clearly in Montana) & not marrying "the boy from across the way"  that she knew in school.
