Another problem one must deal with when stuck out in the wild for an extended period of time, is to be able to find fresh water. One can go without food for weeks, but without water for only several days. Even if there are no lakes or rivers in sight, there are always places you can find water. Certain plants hold water in their stalks, there are also hidden springs around. Knowing where and when to find water is a must have skill for anyone who plans to travel in the wilderness.
