Nominally, a Ranger is an outfitter, a guide, a teacher, and a mentor—a person who takes on a crew of young adventurers, leads them into the Philmont mountains, and points the way until they are ready to function on their own. The Ranger welcomes and orients crews, helps them pare down personal and crew gear until each person has a manageable load. Once on the trail, the Ranger introduces the crew to local conditions and methods of low-impact camping, and reviews essentials of camping, hiking, first aid and safety. The Ranger may point out the trail the first day or so, but the real objective is to ensure that the crew can find its own way.

The Ranger may also convey something of the "magic of Philmont"—of the beauty and wonder of the mountains, the varied flora and fauna, and the history that lies strewn about in the form of old mines, overgrown railroad beds, and the tumbledown ruins of logging camps.

In reality, the experience of being a Ranger is more than the job description. Rangers are known for their high spirit and a can-do, will-do attitude. In the face of hardship or challenge, they are more likely to be energized than discouraged or defeated. If needed to clear trail after a blowdown, fight a wildfire, search for a lost camper, or carry a litter off a mountain, they are ready.

The shared experience of being a Ranger has a way of creating lifelong friendships and forging bonds of understanding, even among Rangers of different eras. The experience can produce a syndrome—probably incurable—characterized by feelings of pride, exhilaration, nostalgia, and longing, lasting years or even decades. It is a phenomenon that can prove baffling to spouses and acquaintances who haven't been there, but it mostly leaves old Rangers remembering cherished friends and places, and thinking, "I wanta go back to Philmont—where the old Rayado flows . . ."
