Something's rattling small Wisconsin town - CNN.com (CNN) -- Mysterious explosions. Unexplained shaking. Something's going on in Clintonville, Wisconsin, but nobody seems to know what it is. The sounds -- variously described as rattling pipes, clanging metal, thunder or firecrackers -- have continued on and off since early Sunday night in just one part of the small town of 4,600, located about 180 miles northeast of Madison. Accompanying the sounds are vibrations that have shaken homes and household objects in the northeast corner of town, city manager Lisa Kuss said. ==================================================================== Is Scott Walker is assembling the death star underground?
