Evergreen Terrace (renamed Homer Simpson Boulevard in a deleted scene) is the street that the Simpsons live on. The Simpsons usually are mentioned as residing at number 742. Therefore, the Flanders live next door at number 744. Evergreen Terrace also has its own exit off the highway.
Former President George Bush lived across from the Simpsons for a short while, and moved quickly because of them, only to be replaced by Former President Gerald Ford, who Homer seems to like, though it is later mentioned that he moved.
