SummerCON.org

Summercon is one of the oldest hacker conventions, and the longest running such conference in America. It helped set a precedent for more modern "cons" such as H.O.P.E. and DEF CON, although it has remained smaller and more personal. Summercon has been hosted in cities such as Pittsburgh, St. Louis, Atlanta, New York, Washington, D.C., Austin, Las Vegas, and Amsterdam.
