1958 Albuquerque rodeo/horse show

Difficult to tell just what this is exactly....the film box was dated 1958, and it's clearly in Albuquerque, New Mexico.....a horse show? A rodeo? Combination? Events at the State Fair (at the old fairgrounds, not the current Expo NM). Maybe someone will see themselves and let me know..... Taken from silent 8mm home movie film.
