Rodeo fans from all over the region are gathering in South Dakota for the 69th Annual Crystal Springs Ranch Rodeo.
The famous small-town PRCA Rodeo is located 7 miles Northeast of Clear Lake, and draws large crowds every year.
The after party got a little out of hand Friday night.
Campers on the scene told us that a young man was stabbed in the abdomen, presumably with some kind of box cutter.
The State Division of Criminal Investigation tells us the victim is in the hospital. No word on his condition at this time. One man has been arrested and is charged with one count of aggravated assault.
