A Winneconne teenager is okay after driving his snowmobile into open water on the Wolf River. Fremont Police say the 18 year-old went into the river under the State Highway 110 bridge in the Village of Fremont around 5pm on Saturday. The snowmobiler was able to swim to shore with some help from bystanders, who wrapped him in a blanket until medical personnel arrived on the scene. The young man was treated by emergency responders and then released to a family member. The Wisconsin DNR will investigate the incident.
