Amusing and informative, Hey Ranger! teaches as it entertains with tales of boat ramp misadventures, lost Afghani campers, encounters with wild animals, dumb crooks, and more. One chapter, 'Tales from the Wild Side,' brings together unusual incidents from National Park Service reports, and the concluding essay, 'Don't Be a Victim of Your Vacation,' advises visitors on how to avoid being a story on the evening news.
