Incidentally, the answer is no.... That's why we love books, magazines, and other information.

Dry facts from books, maps, and magazines is what keeps us, well.. dry, i.e. we don't want to go down by getting our hulls cut open by a rock or another hard place. So safety is a major issue and that's why we collect good maps, good books, and stories and narrations by people who have done it already.
