The Dallas Cowboys first settled at their CLC training camp in the 1963 season. Bob Lilly, a defensive tackle for fourteen seasons (1961–1974), described his time at CLC in his memoir "A Cowboy’s Life" (2008): “The mountainous terrain surrounding the college was beautiful. Every day in the late afternoon we would jog over the mountains. Behind them stood a large ranch that was home to many movie sets. As a matter of fact, the TV series "Gunsmoke" was filmed there as well as the reenactment of the historic flag-raising on Iwo Jima.” The summers at CLC originally consisted of two daily practices – one at 9 am and another at 3 pm.
