Melanie struggles with her riding. She's really had a hard time with her leg and trying to get comfortable on the horse.
She also has had fear issues and more than a few bad experiences. Some injuries, too.

What you saw yesterday is the result of someone who was willing to work hard, learn from good coaches, and keep a positive attitude even when it wasn't going well.
