In the small mountain town of Inez, Kentucky, Mickey and Nina McCoy watched the news footage with their own sense of foreboding.

Mickey and Nina say that event pushed them to demand clean water, and fight environmental degradation in Appalachia. Also, an update on an attempt to make a car that can reach 300 mph.
