I just had to pop in here. My first horse (that was my very own) was a little Morgan mare. I got her for my 13th birthday. She was 14.2 and around 18 years old when I got her. She would run. Me. Ragged. She was always in a hurry. She would leap over absolutely anything I pointed her toward. She was hard to ride but she made me a WAY better rider at a young age than I could have ever been otherwise. Gosh I loved that horse.
As you can see here she would get a little...exuberant about even small jumps, lol.
I was already starting to outgrow her here. I moved up to a 16 hand Appendix QH. My legs are very, very long now, lol.
