By Casey Nelson Jan 26, 2021 7:39 PM FOND DU LAC, WI (WTAQ) â Winter driving is a yearly struggle for many people in Wisconsin, and Fond du Lac County has been seeing their fair share of vehicles off-roading into snow banks in recent weeks. âThe road looked just wet, but we were right in that temperature range where that fog and mist touched the surface of the ground and instantly froze and caused basically a giant skating rink out on the interstate. It caught a lot of people off guard and we had a lot of crashes,â said Fond du Lac County Sheriff Ryan Waldschmidt.
