CASTLE ROCK?
There were originally 40 DC boundary markers ordered erected by George Washington in a 10 by 10 square mile diamond shape. First and 10 on the 40?
First arrest, plus 10? On the 40 = DC?
Was looking into CASTLE ROCK on this and found the WH )castle) is built of the same limestone used for the 40 DC BOUNDARY markers. The quarry is 40 miles down the POTOMAC on Government Island at AQUIA CREEK.
Just sayin.
