BILLINGS- Firefighters in Billings were out braving the frigid temperatures and water Saturday as they practiced saving lives.
In a Facebook video, the firefighters were practicing rescues on ice about 10 inches thick.
They demonstrated that ice can feel thick enough to walk on but still unreliable.
Billings firefighters also warn residents to use common sense and extreme caution when fishing or recreating on the ice.
Also, do not allow animals on the ice, they say.
