One could also point to the Mid-Atlantic area with its plethora of large and small lfs's and various organizations. In a 2 year period there was or is the National Conventions for; AGA, MACNA, Killies group and Catfish Group. Locally one can find; Greater Washington Aquatic Plant Assoc., Potomac Valley Aquarium Society, Capital Area Cichlids, Chesapeake Killifish Club, Chesapeake Marine Aquarium Society and Washington Area Marine Aquarium Society. Obviously to support that many organizations and shops there would have to be a sizable population of "Fish Geeks"
