Another picture from osulmb. In the original post, this picture is labeled as being from 1962. It's one of the few color pictures I have ever seen from that early.
If it is from the 1962 season then I have no idea who the opponent is. Incredibly, we played eight home games that season, and only two on the road. So the opponent could be Colorado State, Washington State, West Texas A&M, San Jose State, Texas-El Paso, Utah State, Utah or New Mexico State.
