I' m another victim of going through the ice. I slipped off a beaver house in late November while moose hunting. Broke completly through, went upside down underwater and wasn' t quite sure which way was up. I got back in the boat and had about 10 miles to go upriver to camp. The only thing that saved me--it was about 10 below at the time and my clothing froze solid and helped insulate me on the trip back. The one thing I remember the most is how bright it is under the ice.
