As a Hoosier (a person from Indiana) I've always thought the same thing. We never called a pizza a pie. When I was young, though, I saw the term "pie" used in a Nancy Drew novel, and I've seen the phrase "pizza pie" as well. Obviously they're related, and equally obviously there's some regional variation, but ... whatever the region is, Indiana is outside it.
