I was 40 ft away when I heard my 13 year old daughter's head hit the ground. It was my worst nightmare. After taking a jump, her stirrup came loose and I helplessly watched her fall followed by a horrible thud. I have no memory of getting to her, but by the time I did, she was back on her feet. Although a bit shaken, she was fine and her Troxel helmet had only a smudge of dirt. She will never ride in anything but a Troxel!
