“WisCon is a 1,000-member science fiction convention with a feminist/social justice focus. Every year we celebrate, dissect, and transform speculative literature, television, film, comics, and games. We specifically aim to foster conversations about feminism(s), gender, race, disability, and class.”
Wiscon has a strong academic track as well as fannish programming. May 26-29 in Madison, WI.
