Greetings friends! I am looking for a beautiful outdoor venue in the greater Baltimore-Washington area for a workshop in mid-October. Doesn't need to be a private space, but would need to be a natural area that is fairly extensive where total privacy is possible. Cabins are a big bonus. Water nearby is also a big bonus. Anywhere between Frederick, MD, Fredericksburg, VA, and Easton, MD is great. Suggestions?
