The first horse I began taking lessons on was a 30 year old morgan, but he was a stockier, taller type. You would have never known how old he was from looking at him or riding him, he still jumped! I find there is an enormous amount of try in the breed and they generally seem happy as long as your happy. I ride a 9 year old 14.2 green broke morgan gelding now, and although he is a sweet, he does have ADHD, an extremely choppy trot, and carries his head either awfully high or extremely low. He really acts as if he's a lap dog, and he can trot or canter for miles and miles without huffing and puffing. They are strong, sturdy, dependable little buggers.
