I never heard of him or Mercer County Equine Rescue. I don't claim any great knowledge of equine rescues, but Mercer County (Harrodsburg) isn't that far from Lex. and only about 15 miles from the main equine rescue in the area, KY Equine Humane Center.
For additional info, I'd suggest you call Cindy Rullman at KHP, since she is organizing the John Henry Memorial Equine Adoption Fair at KHP in April, and they get a bunch of rescues from KY and neighboring states to bring adoptable horses. Her number is (859)259-4209.
You might also call KY Eq. Humane Center; their # is (859)881-5849.
