VIDEO: Authorities were forced to fully evacuate Lake Wissota State Park Sunday afternoon in order to fight several grass fires. Officials told News 18 there were a few campers at the park at the time, but said no one was injured. They don't know what started the fires, or how many acres they have burned so far, but the Department of Natural Resources is sending officers from Ladysmith to help put them out. Authorities said there's a low fire danger this weekend, which is helping their efforts, but the windy conditions are making it more difficult to put out the flames. They said the fire and smoke isn't incredibly visible from the road, because the flames are in a thicker part of the woods.
