When I was a girl, I had a little mustang mare named Nelliebell. She and I spent many hours ridding in the desert together. When I would ride with my boy cousins on their geldings, she would follow at the back of the "herd"; but, when I would ride with my girl cousin on her quarter-horse mare, she would flat out run that registered horse all day if I would let her. She was the best little horse I every had.
