I came across the following brief post about the Catoctin Mountains and the strange activity associated with the overall location. For those unaware of the area, Camp David is located within the mountains and the nearby Cunningham Falls State Park (Thurmont, MD).

NOTE: I have spent a lot of time fly fishing in the natural trout streams located throughout the Catoctin Mountain Park. I have also experienced a few unexplained events as well. The writer mentions the 'will o' the wisp' activity, strange lights that seem to dance along the streams. Most folks would say that it is simple phosphorescent lights seen over marshy ground, thought to result from the combustion of natural gases. But I usually sensed that it was more than that on most occasions.

The general area, north to south, has a heavy imprint of energy from the American Civil War. But there is also a bizarre mix of energy resulting from more recent military and political influence...be it Raven Rock to the north extending southward to Camp David, eventually ending in the District of Columbia, Langley, VA and the Pentagon.
