Reiss says the Springfield where the show is set is "nowhere." He explains the writers chose Springfield as a location because there are more than 40 cities and towns that share the name across the U.S.
Fans have highlighted references to the Bay State in the show, including Mayor Quimby's New England accent and jokes about Harvard. Reiss is proud of the success of the show, whose 30th season will premiere this fall.
