Looking for old horse "Brown and Mild" aka Hal

About 8 years ago I had to give my horse Hal away. I donated him to a family that rode near Foxlair Farm, in Waldon, NY. He was a bay with a star. He would be about 20 years old now. I tried to contact Foxlair but the records of who owns him were lost. I just want to find out how he is doing. Thanks!
