The opening of that new type of summer resort known as the dude ranch, with its three R’s—riding, roping, and roundups—called for an entirely different type of wardrobe.     
   
Appeal of the Dude Ranch
“Dude ranching today is built around its three R’s as
inevitably as schooling. Here, they are
Romance, Rest and Recreation;
and the greatest of these is Romance”

The air was cracklin’ with the cold, And the clouds were fixin’ to snow. It was icy and late on the Interstate So I pulled off into old Elko. I rolled through town just to look around, But there wasn’t much a-happenin’ ‘Til I took a wrong turn and ended up At a Cowboy Poetry Gatherin’. 
 
It used to be that a degree in cowboying from the school of hard knocks required only mastery of the three Rs: ridin’, ropin’, and ‘ranglin’.

There were 9 rodeo cowboys from throughout Texas competing in the Saddle Bronc rough stock event at the 2:00 P.M Sunday afternoon March 28, 2006 performance at the rodeo grounds in Hubbard, Texas. The rodeo was produced by the Cadillac Rodeo Company and sanctioned by the United Professional Cowboys Association and Cowboys Professional Rodeo Association.The rodeo fans also enjoyed many of the other rough stock and timed sanctioned events such as team roping, barrel racing, steer wrestling, and calf roping. The bucking bulls and horses provided great wild western action in the spirit of our unique American western heritage. All the cowboys and cowgirls competing in the various events displayed superb horsemanship and riding skills, demonstrating the basic three R’s of roping, riding, and rastlin’.
