My own convention activity during the 1980s consisted of going to see a couple of Doctor Who conventions in Chicago, but I love to read stories of the early days, from the first convention in 1939 onward, of all the fans and what they did and how they arranged the cons.
To that end, Michael Sinclair, very active in fandom in the south (Chattanooga, Nashville, Bowling Green, et al) during the 1970s and 1980s, is very kindly writing up reminiscences of those times, and also contributing photos of convention badges, programs, etc. which I've put on Collection pages.
It's a wonderful trip back into the land of Nostalgia.
