Everybody knows about the big ones — the American Medical Association, the National Rifle Association, the American Association of Retired Persons. But most of the 125,000 clubs in this society of societies are small, specialized and relatively unknown. The Jim Smith Society (for men named Jim Smith). Frugal, Responsible, Unpretentious, Mature Persons (FRUMPs). The National Association for the Advancement of Perry Mason. The National Organization of Mall Walkers. There's a club for every interest. So if you have that left-out feeling, don't despair. Even if you're a little strange, there's probably a society of souls just like you.
