The Professional Bull Riders (PBR) is a more recent organization dedicated solely to bull riding. Rodeo gender bias was a problem for cowgirls, and in response women formed the Girls Rodeo Association in 1948 (now the Women's Professional Rodeo Association (WPRA)) and held their own rodeos. The Women's Professional Rodeo Association (WPRA) is open exclusively to women. Women's barrel racing is governed by the WPRA, which holds finals for barrel racing along with the PRCA with the cowboys at the NFR. There are associations governing children's, teen, and college level rodeos as well as associations governing rodeo for gays, seniors, Native Americans and others.
