Of course schools, governments and businesses are closing Wednesday because of frigid temperatures. But it will even be too cold for the Lake Geneva Ice Castles. The popular attraction opened last week and has sold out weekend tickets for the next several weeks. But because of dangerously cold temps and wind chills, the Ice Castles are taking a break. Folks who already bought tickets for Wednesday were given refunds and the chance to reschedule their visit. Even though the next day is supposed to be really cold, too, the Ice Castles are scheduled to reopen Thursday in time for Lake Geneva’s Winterfest.
