My friend and mentor Freeman Tilden, the father of the art of interpretation, bemoaned the perversion of the meaning of amateur. He said that "to most people it means a dabbler, a bungler, a producer of something inferior." Yet, it originally described someone who was doing something for the love of it, not for material gain, fame or notoriety. I was a "professional" naturalist for The National Park Service for more than thirty years, but I was really an amateur, and a very happy one.
