BAY CITY, Mich. - A Coast Guardsman helps a man who fell through the ice on Lake Huron near the Bay City Recreation Area Jan. 27, 2011, as part of a four-day ice rescue training class. Night time training is important because the majority of ice-rescue cases happen at night, and responders who have to locate and rescue a person who fell through the ice at night are faced with additional obstacles.
