For seven seasons, the cast of Parks and Recreation sought to improve Pawnee. The fictional Indiana town has come a long way since Leslie Knope turned that pit into a park, and so have the people who live there. Leslie herself has gone from local deputy director to running the Midwest regional parks department. Andy Dwyer went from bum on a couch to owning his own karate dojo. Even Jerry has moved ahead in life from Larry, to Lenny to Interim Mayor of Pawnee. The series airs its final episode Tuesday night. While everyone is struggling to come to terms with saying goodbye, viewers can all take comfort in knowing the show’s spirit will live on — just like Little Sebastian.
