Whenever a horse arrives at Mill Creek Farm in Florida, Peter and Mary Gregory make the aging animal a promise to last the rest of its days.

“We say you’ll never be worked or ridden again,” said Peter Gregory, director of the farm. “And you’ll be here forever. And they are here forever because when they die here, they’re buried here.”

Nearly all of the horses have worked for years in law enforcement, military or other service jobs; a few have been seized by police.
