A Chicago area regional convention founded in 1974 and held annually since then. In recent years, it has ordinarily been held on the weekend closest to Veterans Day. Membership is consistently just above or below 1300. ISFiC, Inc. is the corporate parent.
Windycon was originally founded in order to raise the profile of fandom in Chicago in preparation for a Worldcon bid. In 1982, Chicon IV was the result. From its small beginnings, Windycon has grown to have an annual membership hovering around 1300. It is the largest of the fan-run Chicago conventions.
Annually since 1986, ISFiC has hosted the ISFiC Writers Contest in conjunction with Windycon, open to unpublished authors. The contest is judged by professional authors and editors.
