So I tried googling the glaring geographical error and the only thing I could find was about it was this entry from IMDB:
Dr. Erskine says he is from Queens, NY, 73st and Utopia Pkwy. This is incorrect as both streets run North-South and are about 5 miles apart. The correct Street is 73Ave which does cross Utopia Pkwy.
I doubt that's what you're talking about, as that is not common knowledge and I'm super curious as to what you were talking about.
Anyone else that knows is welcome to answer, I just know she's the one that originally said it.
Thanks!
