VIDEO: Almost a dozen fire departments responded to a fire on Ridgeline Trail on Wednesday afternoon. The bitter winds and extreme cold made it hard for crews to combat the fire. "The weather is making it very difficult to conduct firefighting operations. We were lucky all the hydrants worked, but the smaller hand lines are still very hard to keep flowing water," Menomonee Falls Battalion Chief Kurt Harthun said. Helmets and gear were frozen solid. “The ice makes a little of an insulator, but it does make it hard to move," Harthun said. A thick layer of ice encased the ground, creating slippery conditions. To keep warm, crews took turns rotating inside a warming bus and ambulances.
