That is the question I asked myself a few years ago, back in 2002. I saw the brochure at the LFS (local fish store), and heard some people talking about it, but I wasn't sure what it actually was. One thread on ReefCentral asked "Who's going to MACNA this year?" and so I finally replied that I wanted to know what it was all about. Duane, one of members of DFWMAS, chimed in that it was being held in Ft Worth, and that I would love it. Skeptical, I decided to do more research.
