My brother got me this book for Christmas since we're planning to do an adventure race this fall. I can read a regular map (though, to be honest, it takes way more thought and concentration than it should), but navigating by compass and topographical map is not in my skill set.
While the book isn't subtitled "Orienteering for Dummies", that's basically what it is. It's a short book and quick read, with clear explanations. It's filled with illustrations and interspersed with short quizzes to make sure you're getting the concepts. Of course, reading about navigating is no substitute for actually doing it, but this was a good introduction for me. If nothing else, I'll have a better understanding of the race reports I've been reading. I'm looking forward to actually practicing some of the concepts on our next free weekend, when I'm hoping to drag my husband out to Rockwoods Range, which has a permanent orienteering course.
