Walmart's closures leave gaping voids throughout small-town America

To hear Mary Francis Matney tell it, Walmart didn't kill the once-vibrant cluster of shops next to a railroad and a creek in the faded old coal town of Kimball, W.Va. -- the disappearance of the mines had pretty well taken care of that already. But now that Walmart is leaving, too, as one of 154 U.S. stores the company closed in January, the town might be snuffed out for good.
