I saw a preseason (called "exhibition" back then) game between Denver and Kansas City in 1964. Saw Mike Renfro play for Heights when I was in grad school.
I saw Norm Bulaich win the 100 yard dash in the mid-60's for TCU: Compared to the other sprinters it looked initially like a shot putter had gotten mixed up and appeared on the track; then he smoked those little guys. This was in an annual Spring competition back then for both high schools and colleges: "Southwestern" something-or-other, which included events all over town, including golf.
Also, on a more disturbing note, the bulletin board (changeable letters like old theaters), would tell which games were to be played, including the "Colored" high school games, usually on a Wed or Thurs, I think.
Still a beautiful old stadium of the Art Deco style so popular back then. I love Art Deco and am happy they kept it at ACS.
