(Whitewater Valley)--Earlier this summer, the U.S. 40 yard sale covered the Whitewater Valley from east to west. Thursday morning, the U.S. 127 yard sale kicks off on a four-day schedule that runs from north to south.  The yard sale cuts through the heart of Preble, Darke, and Butler County on its nearly 700-mile run from Michigan to Alabama.  The yard sale runs from Thursday until Sunday.
