Watson would settle for second while Lee Schuler of Lockport, Ill., would finish third. Bob Anzinger of McHenry, Ill., would take fourth and Vaughn Gerke of South Beloit, Ill., grabbed fifth.
May 28 – The North Iowa Speedway in Mason City, Iowa, was the only track in the area not postponed by rain so all of the top drivers from northern Iowa and southern Minnesota showed up to do battle for the Memorial Day special.

It was Bartholomew’s first trip to the North Iowa facility and only his second career late model victory.
