One of the top local riders, Louise Serio of Kennett Square, was unable to take part in the Devon Horse Show because one of her horses was ill.

Serio, who was featured in a May 18 Inquirer story about the Devon show, was unable to compete as planned in the International Hunter Derby on May 25 and in Memorial Day's regular working-hunter event as well as the first-year green-hunter event.

Serio's horse, Castle Rock, was sick with a fever and was unable to be transported to Devon from its home in Tampa, Fla., in time for the show.

Another horse, Lafayette, which she planned to ride in the first-year green-hunter event, is housed in Wellington, Fla. She said trailer transportation costs made it prohibitively expensive to transport just one horse.

Serio, 54, has competed in the Devon Horse Show almost every year since she was a child. She was the 2001 Chronicle of the Horse's professional world championship hunter rider and the 2006 Chronicle's show hunter of the year.

Though she was not able to compete this year, Serio said she was at the show helping other riders and intends to participate in next year's event.

"I'll come back even stronger next year," Serio said.
