I just wanted to contribute this link to interested readers of an article written about black rodeo riders living in the town I used to live in, Riverside, California. The article is:

One interviewee complained about how the Black rodeos were racist and misrepresents Billy Pickett's multi-cultural life with the "101." What that person seemed to miss was that Pickett was banned from several rodeos because of his race. It's a good article which covers family heritage of modern participants.
