A critical question is how do you melt the frozen water in the bottles in your kit? All the water bottles, juice bottles etc are plastic. If you heat the plastic it will melt. You can't get the ice out of the bottle as the neck is too small.
Is there a way to keep it from freezing in your trunk or even your back seat?
I have been keeping a winter survival kit in my car for years, but water, left even overnight, is frozen in the morning when you are going someplace. I am taking a trip in a few weeks and since western and central NY weather is very unpredictible I really need an answer.
