Owned By All, second in the Hilltop Stakes at Pimlico, is owned by 28 residents of the Doswell, Va., area. Each put up $300 at the suggestion of horsewoman Ingrid Kampinga.

"I thought we could revive the horse spirit in Doswell, so I went to the Hanover Country Club, asked for shareholders and here we are," said Kampinga. Owned By All has earned $27,000 and is valued at $60,000 as a potential broodmare. She cost $6,200 at a Timonium sale. Trainer Richard Small points her for the Black-Eyed Susan Stakes here May 20 . . .
