NATCAP OUG - or the National Capitol Region Oracle Users Group - has a long history of providing Oracle-related content to those in the DC metro area. I remember presenting there back in my Oracle days (early 2000's) on multiple occasions.
Over the last few months, a few of us have been trying to resurrect this group, as there are likely more Oracle developers & DBAs in the DC area than any other area in the US, perhaps even the world! This region has long been underserved, and we hope to change that.
We have had a couple of meeting at Oracle's campus in Reston, and attendance has been, well, not where we need it to be. So, if you're in the DC area, please consider joining this group. It's free, and our goal is to have quarterly meetings where both experienced presenters and NATCAP members alike provide the content.

Let's grow this group and give the DC metro area the user group it so badly needs!
