Fort Macon's northern corner: Hallelujia. That lovely light green greenery along the ground represents the dry moat. Fort Macon was originally designed with an actual moat moat, but issues with the gate that was supposed to control the amount of seawater allowed into the moat prompted engineers to fill in three feet, to the level where it is today. A dry moat may not be better than a wet moat, but is preferable to no moat.
