I thought long and hard on this question and started to write a post in my mind and realized that there would be no end to the post. I then thought, the better question is "What part of me isn't ISU?" and the answer is that I can't think of anything about me that isn't ISU.
However, I can reasonably say that my ISU connections go back to before there was an ISU. In doing genealogical research I found, to my great delight, that my great, great grandfather's farm was purchased by the state to become part of ISU in about 1866. He had owned the pioneer farm for quite some time prior to 1858 when the Iowa Legislature officially established the Iowa Agricultural College and Model Farm (ISU).
