I remember all of the games from that year because it was my first year writing for an internet sports magazine.
The two games I vividly remember from that year were the A&M game and the Texas game. A&M because that Saturday was the first we'd spent with my wife's estranged father. He was born and raised in Oklahoma, was intentionally a jerk to me for the entire time we knew him and thoroughly enjoyed A&M beating us. Very child like.
The Halloween Texas game I remember because we'd just moved into a new house and didn't have cable yet so I had to go to a local sports bar to watch the game. This was in Parker Colorado, so a Nebraska fan watching Nebraska lose in a Colorado sports bar was also thoroughly enjoyed by others.
Also of note, that was the first year since I'd been watching Husker football (1970) that we lost 4 games. 1976 NU went 9-3-1.
