Actually I think the map shows the dominant dialect/accent, it doesn't deny the existence of others. The entire west half of the continent is one color, but off the top of my head I know at least five distinct accents you can find among white people here. My grandmothers we're both born and raised in Washington state and had distinctly different speech patterns. My father's mother's accent was almost British, but I can clearly remember my mother's mother talking about "worshing" up or going down to the "crick".
