I can't find a Category for people who participated or competed in rodeos. There is a Category for Cowboys, and certainly many people who competed in rodeos were cowboys first. Seems like a Rodeo Category should fall under Occupations, because most people who participate in rodeos are making their living earning purses. But, I'm hesitant to create the Category myself, as I'm not sure if I'm on the right track, because perhaps they are considered performers instead?
Some examples of profiles that should have some type of Rodeo Category:
Knight-9748
Cooper-11682
Greenough-339
Danks-210
Hudson-8238 (ooh, she's unconnected, might work on that one)
