Loss of feel - oh gee do you think? But, as the caption suggests, they may also have met something extremely scarey on a blind curve.
A friend, who rides one of the most solid horses I've ever been around, nearly came off when she met a dirt bike coming around a tight corner on a narrow trail, almost a tunnel in the forest. The guy said "I can't believe you would ride a horse up here." She apparently heard the bike, but couldn't believe it was actually coming up that steep narrow trail. Prize probably looked a lot like the horse in the photo. Nancy
