Noteboom cashes in at Memorial Clash

JEFFERSON, S.D. (May 26) – Jay Noteboom trumped a stout field of 24 Artworks Graphics IMCA Modifieds to take home the top spot and $1,500 at Park Jefferson Speedway’s Memorial Clash.   At the jump, it was Chad Ten Napel jumping out to the early lead followed by Bob Moore and Chris Abelson.
