Great Trail Horse With Potential

5 year old solid sorrel paint mare. APHA registered breed stock mare. Green Broke to ride. For an avanced rider to teach her new things. She has a star and snip no other markings. She is sweet and learns fast. She walks and trots under saddle. She does not know the cues for cantering under saddle. Great and used for Trail riding. She stands for the farrier, no bucking or rearing when riding. She is 15 hands tall. We need a more beginner horse, because she needs someone who can teach her more.
