Ben Johnson: Team roping world champion. Two Rodeo Championships: Tie-down Roping and Team Roping both in 1953.
"Hoot" Gibson: 1912 All-Aroundl Pendleton World Champion Cowboy
While most people are more familiar with Academy winner Ben Johnson, Hoot Gibson was an earlier cowboy who was in silent movies and a romantic lead. I best know him as one who carried a six-gun in his boot, so when the bad guys got the drop on him and his buddies, he would turn the tables on them when he pulled out his gun.
