She is a 4 year old girl that we  have been using for about two years. We have used her  to work cows, trail ride ,and hog hunt.She is accustomed to crossing rivers and  streams . She has also gone through quick  sand and thick brush. She neck rains fairly  but has some rough edges such as tossing her head and gets somewhat stiff at times. She trailer load  well and stands tied. She has been around all kinds of animals and gone through all  kinds of terrain. She is also accustomed to gunshots and we  can shoot off of her back.
