Camp David, the US Presidential Retreat
also known as Naval Support Facility, Thurmont, in Thurmont, MD 21788 is 125 acre mountain retreat of the President of the United States. It is just across the Pennsylvania border, not far from "Site R" (Raven Rock), the Alternate Joint Communications Center.As it seems there is no better zoom resolution available - understandable as it is a top guarded military site. More about it in this discussion or on the Wikipedia page.
