1992 was the Halloween Night Massacre when NU beat CU 52-7. It was a night game, but wasn’t raining.
1994 NU-CU was an 11 AM kickoff at home.
1996 was a dreary 2:30 kickoff on the day after Thanksgiving. CU replaced OU for that date when the Big 12 was formed. It was cold and wet day. Very close game. Neither team could get much going offensively.
1998 was very much the same as 1996. Cold and wet. 2:30 kickoff that ended in the darkness of the early evening. Another close, hard fought defensive battle.
