SCAPE is a great club. We do have a meet once a year at Lotus Aquarium in Lawndale, which I do believe is close to you. We meet at different locations every month hosted by members or sponsers. Then there is COAST, which meets every 1st Sunday of each month in Costa Mesa. Monthly speakers and great auction. There is also the SOCAL Killi club which meets in Seal Beach and Glendale area, alternates between the sites each month.
All of these are like 30 Miles plus. I really thought there were more clubs around. I guess not. When I had a reef tank I could find a dozen clubs in 5 miles but nothing for Freshwater..Really disappointing.
