:Wikipedia is an encyclopedia, not a repository of pop culture, and articles need to be written with that in mind. This article already discusses how the show has mentioned numerous contradictory bits of geography. There is no reason to mention any one in particular, because none stands out from the rest. We can't list them all, because doing so would vastly lengthen the article. The only practical solution is to mention none. Note that the article does cite Flanders' quote from The Simpsons Movie as an example of the impossibility of locating Springfield (which is slightly different from what we're talking about).
