COLUMBUS, Neb. (AP) — The new manager of the Platte County fairgrounds has quit after just one day on the job.

Platte County Agricultural Society chairman Kurt Muhle said Jim Cockson quit on Tuesday after starting on Monday. He accepted the job on June 28.

Muhle says Cockson decided for health and personal reasons that he couldn’t stay. Cockson didn’t immediately return a call Wednesday from The Associated Press.

Rick Johnson will continue to serve as interim general manager until the society board of directors selects another candidate.

The county fair, which opened Wednesday, runs through Sunday.
