October 8, 1966 with my dad and a couple others when I was 7 years old. We beat Ohio State 10-9, never will forget it. Illinois had a lot of bad losses that year but beat both the Buckeyes and Wolverines. MSU was the powerhouse in the conference that year with Bubba Smith. They played the infamous tie (6-6?) with ND that year which ended up with ND winning the national championship. I was forever hooked on the Illini after this though.
