Horizon Farms, a fixture in the Barrington Hills, Illinois, community for 25 years, will cease its breeding and boarding operations in September.

"Everyone is sorry to see it happen, but this is not a moneymaking proposition," farm manager Sharon Wilson told the Chicago Tribune.

The operation at the 400-acre farm had been losing steam since the death of its founders, William and Jane McGinley. William McGinley, owner of Methode Electronics Inc., died in January 2001, and Jane McGinley died in February 2003.

Two of the McGinleys' three children live outside Illinois, and none are interested in continuing the farm's boarding and breeding operation. Neither are they interested in selling the farmland to developers, who have turned much of the Barrington Hills rural landscape into subdivisions of million-dollar homes.

"We have to close the estate, but …we don't exactly know how it will work out," said son Robert McGinley, who lives in California. "The goal is to keep the farm out of development."

Horizon has one of the state's top stallions in Unreal Zeal, who stands for $3,000. The 23-year-old son of Mr. Prospector is the sire of 23 stakes winners. Horizon boards 125 horses and 62 foals have been born this year.
