Thanks.

I've heard of such horror stories, even recent ones. We can get a few days in a row each winter with daytime highs of 10F and nighttime lows of -25F, but only 3-5 days in a row at most. Still wouldn't want to be caught in that unprepared. Imagine a day and night of freezing rain before that. Haven't checked out the statistics on that. At least we have some trees to burn here. Still, good in theory, but practice usually takes some practice.

Remember the scene in Never Cry Wolf where he falls through the ice after getting dropped off. Now that would be terrifying.
