 Because the first con run by the organization was not actually named ConFusion, they are generally counted starting with ConFusion 13 in 1975 (one of many intentionally confusing names voted on by the membership).The 1980 con was aptly named Confusion 6 &/or 7, and ConFusion XXX in 2004 could be considered the 30th convention of that name, or 31st Stilyagi con.The Stilyagi Air Corps, named after a group in Robert A. Heinlein's The Moon is a Harsh Mistress, is a loose, informal group, lifetime membership is free for anyone interested in Science Fiction who attends a single Stilyagi party, meeting, or event.
