A scary chain of events at Leif Erickson Day Camp in Sioux Falls sent eight people to the hospital.
Sioux Falls Fire Rescue was called to the camp when a horse bucked a girl off during a trail ride. That set off a chain reaction and a total of seven girls were knocked off their horses too. One of the girls was unconscious.
Authorities say eight people were taken to the hospital, including one counselor; most of the injuries are bumps and bruises.
