The River Wild - Near Sacramento

According to the Sacramento Bee, Saturday's "Rafting Gone Wild" event on the American River "degenerated into a series of brawls with dozens of rafters fighting each other with oars and rocks and hurling stones at deputies on the scene."

More than 3,500 tubers--many with floating coolers stocked with beer--turned out for the second annual event on Saturday, officials said. At about 5 p.m. local time, approximately 50 rafters began fighting on a beach area along the river, Sacramento Metropolitan Fire Dept. deputy chief Scott Cockrum told the newspaper, "beating each other with paddles or rocks and hurling stones at fire and rescue boats."
