This is exactly it. I keep protein bars, sugar-free Gatorade, and water rolled up in a winter-rated sleeping bag and then wrap a blanket around the sleeping bag. I also have a shovel and a small container of salt that works in frigid temps.
And if you run out of water, you can always grab some snow.
How do you keep the Gatorade and water from exploding when they freeze if this was for a car, or was this comment for Amtrak travel? I have heard of opening up drinks and pouring some out to leave headroom for expansion...
