the air just to survive. we spoke with family and friends from louisiana late yesterday. they d just come back from the campground site. there were nine people in their all, all got out alive but they were still bloody and bruised from their ordeal, just thankful to be alive. for folks who might not have heard too much about this over the weekend, how fast did that water come up and how deep did it get? reporter: well, the little missouri river normally is about three feet deep. that s what what it was at when the rain first hit friday night. excuse me, early friday morning. it then rose to a level of more than 20 feet within a couple of hours. as i said, this was while people were sleeping so it just there was no ability very little cell phone service in this area. there was no ability to warn those folks. so many of the survivors, the only warning they got is the noise that they heard outside of their tents or outside of their rvs. many of them say they thought it was wind. b
