Bearded men wearing suspenders and straw hats stacked cinder block after cinder block as heavy equipment quickly moved lumber. While most of the region prepared for July 4 picnics and parades, the men worked through lunch Friday, picking up pieces of a barn blown down the day before. “Oh, it was quick,” said Ben King, 37, the Amish farmer who owns the farm on Fordsbush Road in the town of Minden in western Montgomery County. “I can’t tell you what it really was, really. It was so quick.” After surveying the damage Friday, the National Weather Service determined that the winds were not from a tornado, but rather were straight-line winds that reached 100 mph.
