This weekend, two popular western riding shows will celebrate milestone anniversaries.They are the 20th annual Professional Bull Riders World Finals in Las Vegas and the 60th Roping Fiesta in San Angelo.But each show has its own type of fan.The PBR championships will pull in the same type of people who follow NASCAR. The Roping Fiesta will lasso dyed-in-the-leather rodeo fans.Many of the PBR aficionados have no rodeo, ranching or agricultural background, but they can get into bull riding because of its simplicity. A rider attempts to stays on a bull for eight seconds, plain and simple.“It does not take a massive education about bull riding to follow it,” said Pam Minick of Roanoke, a longtime TV commentator who helped with the PBR broadcasts in the 1990s. “It’s also an extreme sport. Fans come not wanting to see anybody have a wreck, but they sure want to be there when it happens.”The PBR World Finals is scheduled for Wednesday through Saturday at Las Vegas’ Thomas & Mack Center. The show will feature 35 competitors including Decatur cowboys Mike Lee, the 2004 world champion, and Silvano Alves, who will attempt to become the first athlete to win three consecutive PBR world titles.Alves, a Brazilian, is ranked No. 1 in the Built Ford Tough Series world standings with 10,917.75 points. North Carolinian J.B. Mauney is ranked No. 2 with 10,379.25, and Brazilian Joao Ricardo Vieira is ranked No. 3 with 8,788.73.In San Angelo this weekend, the Roping Fiesta devotees are purists who appreciate a great cow horse and a cowboy who can handle a rope. They’re the same people who travel to Fort Worth each Memorial Day Weekend for the Windy Ryon Memorial Roping. And by the way, the renowned Ryon Roping celebrated its 40th anniversary in May.“Roping fans take as much pleasure in watching the horses work as they do the cowboys,” Minick said. “They appreciate the heritage of western sporting events. Cowboys still rope a steer today the same way that they did 120 years ago.”Like the Windy Ryon, the Roping Fiesta will feature the sport’s elite such as six-time world champion Cody Ohl of Hico and two-time world champion Tuf Cooper of Decatur, who will compete against each other in the match roping. Last year, Cooper earned $33,800 after beating Ohl and finishing second in the Invitational Calf Roping competition.College rodeo updateAfter competing in the Texas Tech Rodeo last weekend, Tarleton State is ranked No. 1 in the National Intercollegiate Rodeo Association Southwest Region team standings with 1,875 points.
