KENNETT SQUARE, Pa. — Barbaro's owners said they need some time to determine the final resting place for the Kentucky Derby winner.

Roy and Gretchen Jackson, owners of the beloved colt who was euthanized Monday, remained undecided about where Barbaro will be buried.

It could be the Kentucky Derby Museum, near the scene of his greatest triumph in the 2006 Derby at Churchill Downs in Louisville, Ky.

Or it could be in the bluegrass of Lexington, Ky., at the 1,200-acre Kentucky Horse Park. Or possibly the Jacksons' 190-acre Lael Farm, not far from the University of Pennsylvania's New Bolton Center where Barbaro spent eight months trying to recover from three bones that shattered in his right hind leg at the start of the Preakness.

One possibility is that Barbaro's resting place might form the basis of a regional racing museum, Gretchen Jackson said Tuesday night.

"My son-in-law, I think, had this idea that we really ought to get some kind of museum for the horses who have run out of this area," she told The Philadelphia Inquirer. "That sort of sticks in my mind. You'd have to look at that before you decide where Barbaro goes."

Despite the pain of Monday's decision, Jackson said, "There's a certain amount of relief knowing that horse is in a better place. ... I don't have any regrets."

Barbaro's body was no longer at New Bolton. "We cremated him," Jackson said. "I assume it's been done."

At the New Bolton Center, subdued staffers tried to get on with business as usual. It wasn't easy, especially for chief surgeon Dean Richardson, who cared for Barbaro from the start and built a special bond with the colt.

During Richardson's morning rounds Tuesday, there were no bright eyes staring back at him from the corner ICU stall Barbaro occupied.

"I've been getting up before six every morning for the last eight months to look at the horse," Richardson said, pausing to collect his thoughts. "And he's not there. It's kind of tough."
