Here's a link from James L. Rogers Book "The Story of North Texas" page 476. I didn't know that North Texas played home games at The Cotton Bowl in the early '70's under Rod Rust. I know we played Texas Stadium home games over the years, but I've been around North Texas Football since the mid 80's and this is the first time I've read a reference to playing home games at The Cotton Bowl.
Does anyone have more information on this and who we played at The Cotton Bowl?
