I don't crashpad there, but I do believe that there might be room in one of the old ACA/IDE pads around IAD. If you are looking, PM me and I might be able to put you in touch with some of the folks who could help you out.
As a side note, I will have a room/crashpad available in ROA (for incoming PDT crews) available in late April. If you are interested, PM me.
