We have a neighbor who has a kid in The Heights, a private school located at 10400 Seven Locks Rd, Potomac. The boy, who is 9, was exploring the wooded grounds last week when he saw a metal object partially buried. He dug it up, finding it was a (presumably civil war) cannonball, and brought it home. After some amusement, a friend of the family saw in a picture a hole that would have been for a fuse. In other words, it was an exploding shell, potentially unstable. They reported it to police, who brought out the bomb squad, who confiscated the find. The little fella is distraught, they took his cannonball!
It's probably safe to presume this was from Jubal Early's attack on Washington in 1864.
