LACROSSE, Wis. – Probably for the last time this season, crews at Mount LaCrosse have brought out their snow-making machines. The hope: That their manufactured snow will last the weekend for a major race, said Darcie Breidel, general manager. The forecast: Low 70s. In a 48-hour window early in week, Breidel said, there was an opportunity “to pounce” after an usually warm winter and spray the slopes.
