only input i have is i can attest to WA State having nothing but mixed people. Pierce County (where Tacoma is, the blackest city in WA State) has nothing but eggo waffle colored "black" people walking around. Go to any grocery store and all you see is White, Mexican and Asian women with 2-3 mixed children. And the family i have here is majority mulatto...my uncle married a cac in the 70s, had cac kids who both procreated with non black people and 2 of my cousins on the other side of the fam have kids with cacs
