Airs Wednesday, February 5 at 8 p.m. In this episode Al Letson and guest producer Lu Olkowski visit a tiny town in the Appalachian foothills of Ohio where, for a century, residents have shared the common bond of identifying as African-American despite the fact that they look white. Racial lines have been blurred to invisibility, and people inside the same family can vehemently disagree about whether they are black or white. It can be tense and confusing. As a result, everyone's choosing: Am I black? Am I mixed race? Or, am I white? Adding to the confusion, there's a movement afoot to recognize their Native-American heritage.
