The buses were not in service Monday morning. The district superintendent said those parts are very expensive to replace. He said it’ll cost more than $40,000 to fix them. And he said besides the money, the toughest part is telling families the school can’t help get their kids gt to class.

“It wasn’t like somebody made a bad decision and ran off the road,” said Superintendent Jeff Craig. “Or we didn’t pay our insurance or we didn’t pay our gas bill. It was a negative piece that negatively impacted a lot of kids.”
