This is a long running issue with the Wikipedia pages on Springfield and Springfield's State (the latter talks about the real life location). It was established that it is an impossible location (with a source saying so from SNPP). This is not "hard data" as it is from the series, it is in-universe and therefore is not any more reliable than any other evidence from the show. The only thing which will prove beyond any doubt that is somebody involved in the production of the show, in an out of universe context, saying exactly which state Springfield is in. If you look back at the history of Springfield's State you'll see that loads of speculation and original conclusions such as this one were deleted from the article. ● (talk|contribs)
