More than 30 cars’ tires were flattened as they drove along East First Street in Crossville over the weekend and today.  We talked with Shadden Tire who told us they had probably 15 cars with flat tires come in Friday and 15 more thus far today.  They said apparently the cars ran over sharp metal objects that were either accidentally or intentionally dumped on East First Street. We checked with Crossville Police Department who told us they had no report of the incidents as of this morning.
