Beautiful horses! I used to volunteer at a therapeutic riding stable - it lasted for five years and I LOVED it there. I miss "my" horses ... especially Coco. Coco was a purebred Canadian mare, 25 years young. I loved that girl like she was mine. There was also Dora the Fjord, sweet sweet old girl. I think she must have been around thirty. I also used to ride and I miss being around horses so much! I might try lessons again sometime, when I have the chance.
Old young horses are the best! Louie, the horse I ride, is ~21 but you would never know it except he's going a little bit gray in the face. Especially the way he took off on cross country a few weeks ago lol.
