en_captions: There are several people wearing helmets and vests, rowing rafts in the river in the wilderness.  Groups of people are waiting at the top part of the river slope, ready to begin their journey down the river while some other rafters are standing on the banks of the river.  The rafters go down the river through the turbulent water and waves of the river.  The rafters go down the turbulent water trying hard to stay afloat as they combat the rapid flowing river.  They continue rafting down the river as they row through the waves.  Still pictures of some of the rafters standing in the wilderness are shown.
