Hunker Down
The wilderness can be a very dangerous place if you are not properly prepared. A very scary situation some people tend to find themselves in is being stuck in the middle of bad or cold weather, or being outdoors when the sun goes down. If you are stuck in the wild and you know you may be there for some time, you want to make sure you have shelter.
This can be made out of almost anything you find around you. Sticks, moss, branches, and leaves, etc, could all help you set up a temporary shelter. Having shelter will protect you from the elements that could otherwise put you in a dangerous situation.
