Character mistake: When Estelle gives her guest speech about the Tuskegee airmen she shows a slideshow. There is a photo of an airplane that she incorrectly labels as "a single engine P-47." This is not correct. The plane in the photo is a P-39 Airacobra.
Carl, Eddie, and Steve are out ice fishing. At one point Carl falls through the "ice" and you can clearly see that the "ice" is made of some sort of styrofoam. It looks like the stuff used for packaging. The snow looks just as fake.
