UPPER PENINSULA MICHIGAN, (CNN) - Take a look at this video of a rafting trip gone wrong on Michigan's Upper Peninsula; a group of rafters were crossing Piers Gorge when the forceful waters took control of the boat. Onlooker Jason Asselin captured this video for CNN's i-Report; he says the voyage turned frightening as the rafters paddled back upstream against the current.
Apparently, the boaters were in a spot where the river was flowing over a rock. Jason says two people fell out of the raft, but didn't appear hurt.
The instructor eventually got the boat and the situation under control.
