Ethnicity seems to be a touchy, volatile subject.... the fact is that, for some reason, there are not a lot of African Americans (or African origin people of any other nationality for that matter) that are involved in Land Speed racing... NASCAR seems also to be bereft of other than white competitiors... I can't speak for NASCAR (although I did read the story of Wendell Scott.... fictionalized into a movie called Greased Lightning- with Richard Pryor playing Wendell Scott).... but, I do know that Bonneville is NOT ethnically exclusive....
I have been asking why to this for a long time.... I do know that, in the area of Canada in which I live, there just aren't very many people of African origin but that isn't the case in a lot of the USA. So, where then are they?.....
I do know that my youngest daughter was with an Afro guy for a number of years and I have a grandson of African ethnicity.... when he is old enough and, if he wants to, I will be giving him a fair shake at driving the car....
