Fantasy book helps teen survive waterfall

Read here: 'Lucky to be alive,' teen hails rescuers.  Thank God this guy is all right!

The story has been in the papers a few days, but this new article brings two things to mind:

1. Reading fantasy books is not altogether useless or un-educational.  (I never thought it was!)
2. Doing your research is always important.  An author, of course, isn't completely responsible for a reader's reaction, but whatever an author does, they should never needlessly portray misleading information that a reader might easily interpret as factual/sensible/a good idea.

I haven't read the Pendragon series, but lots of adventure books have influenced my notions of what to do in a survival situation.  Now, whether I'd remember what their advice was is another question.  : /
