The northern buildings of Stephens (1969) and Hilton (1971) in the ISC were built first so it makes sense that they numbered from close to those buildings to further away. Jack Trice didn't open until 1975. Even Fisher (1974) opened before JTS.Is it just me or does anyone else wish they started the numbering from Jack Trice Stadium so that A1, B1, C1, and D1 are in a line?
