Nope, I'm not a U of I alum, but my cousins all were hitting U of I starting about then (I still remember SO clearly when my aunt became Mrs. Active Officer in the Parents Club about 2 minutes after my first cousin went "away" to school ... he was very understanding about it, at least publicly). My dad's a Delta Sigma Phi from U of I, one cousin is a Delta Tau Delta ('85ish), his wife (and my dear friend) is an Alpha Gam ('87ish), and my other cousin is a Delta Zeta (also '87ish) -- all U of I. I'm just about the only one in my family who didn't go to U of I, and it's probably only because my leg of the family had left the state by then.
PM me if you want to compare names!!
