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