I used to do SAR. Lost persons do a terrible job of communicating because they are afraid and often emotionally and physically drained. But if you have them on a radio or a cell phone, you can generally locate them without the persons direct assistance.

One of the many things that really annoys me about W3W is that it sucks for actual navigation. If I am at waffle.tire.sigh is that north or south of keys.sad.tree? Am I heading in the right direction?
