I know this is a long shot, but I can't help looking for him. I owned this horse in 2001-2005 and then gave him back to the people I got him from. They turned around and sold him to someone in Claremont, FL. He was a little too much horse for her so she sold him to someone named Rachel Mills in Gainesville, FL.
I have contacted the girl who owned him in Claremont and she said it was her understanding that Rachel moved back to Long Island, NY, possibly to care for her mother. She did not know if Hoo went with her or not. I loved this horse and circumstances forced me to give him back at the time, but I'd like to know that he's safe and offer a home if he ever needs one.
Here is a link to a picture of him when I had him:
