Hillgang (Washington DC area)
Hillgang is the Washington DC/Virginia/Maryland/Delaware-area user group for any operating systems running on S/390, zSeries, or System z hardware (we even have a few members running older systems -- even one real System 360/75!). We meet roughly quarterly (more or less) at the Computer Associates office in Herndon, Virginia.
Anyone is welcome (we're pretty ecumenical).
