Lake Geneva holds an annual Winterfest every year to celebrate all things winter and Appeal To everyone who likes everything cold. You Won’t Be surprised to find out that Cars Fall Through The Ice when it’s not as cold as you think it was going to be. The temperature was around 40 degree’s and the ice can’t hold strong at that warm of a climate. Maybe next time just park 3 miles away and you’ll be tired by the time you actually get to the festival late. Won’t that be a lot better?
