Every Time, Every ride. by LaurenA woman from my barn was on her horse in our dressage arena (NO FENCES!!!!) without a helmet. The horse had a very goopy eye and couldn't see very well out of it, and I was riding in the arena on another horse. The horse she was riding bolted, bucked, and then threw her into a tree. My horse, who was really quiet and sweet. stood there like a little angel.(thankfully) They had to call the paramedics and even now, about a year later, she still has trouble remembering things.
