The horse I ride is a 14 year old MFT mare. She hadn't been ridden much, having been a broodmare for a long time, so she's spooky and green. The first couple times I rode her, she spooked at *leaves*. She's really calmed down since then, though, although she still has a tendency to spook. (Luckily, she usually spooks "in place".) She is very responsive and willing, and she has a good deal of "go" (as well as a very fast walk). Her daughter is in training, as is as calm and levelheaded as can be.
The other horse I ride is an old KMH gelding- totally bombproof- who will nevertheless gallop up every hill if given the chance. His gaits are lovely, but if you let him rack, he decides he never wants to walk again and takes off. He's very levelheaded, just stubborn as... well, a mule. We usually keep him behind a slower horse on trails so he can't take off.
No hour of life is wasted that is spent in the saddle. ~Winston Churchill
