I am in the DC area.
Helicopter High based out of Martin State airport has a 206 ($850.00/hr) but I am not sure he uses that for training.
The closest one that I know of that does do training is based out of Richmond, Va. They move it to Norfolk frequently which is quite a haul from D.C. (Richmond Helicopters and I think $750.00/hour)
There are a few Robbie schools around, Manassas VA, Fredrick, MD and Baltimore, MD
