Well, that's true. You definitely don't need a tarp and a saw. A shovel is good for finding worms and digging your own grave. A smartphone won't weigh you down, but there's no guarantee you'll have internet access. You don't need a shelter either – a hole in the snow with a roof is simpler and more convenient. And you definitely don't want to freeze to death – it's much better to spend a couple of hours wandering around in the dark looking for firewood. Even if you don't manage to find any, you'll still warm up.
