I am a longtime SF reader, and knew of fandom vaguely, but had never connected. Another of my hobbies is mail art and rubber stamps, and one of my correspondents was running the mail art show connected with Janecon, a con that was in honor of Jane Hawkins' 40th birthday. I ended up spending most of the weekend, and had a great time. So now I go to Vanguard , and was Con Suite czarina at Potlatch III and Potlatch 6, and bowled with Jane and Andy and Jon, and do Cacophony stuff with Luke. When I described Potlatch as a sercon convention with a fannish flavor, someone not in fandom asked me what I meant.
Potlatch is more reading or book oriented, as opposed to TV, comics, movies or anime.
Apparatchik was the focal point zine of our time. Jane Hawkins and Luke McGuff coordinated programming for that one. My buddy Luke chaired and Jane and I shared the consuite duties. Cheryl Morgan has some good pictures, though none of me. Don't forget about Clarion West , the workshop for aspiring SF writers.
