Marathon City officials are suggesting people should stay off the Rib River while the water is so high after two teenagers had to be rescued Sunday.  An assistant chief with the Marathon City Fire Department says the two boys were kayaking near Highway 29 and County Road-O when one of the kayaks tipped over.  The other teenager was able to use his cell phone to call for help and share the location with emergency responders.  A rescue boat was used to get them to safety and both were taken to a hospital.  They are expected to recover.  Their names and ages haven’t been released.
