Fort Pulaski has the most impressive moat of any of the forts I've visited to date. That of Fort Delaware is similar, but Fort Pulaski's is cleaner and stretches the full length of the Demilune and fort. Get yourself a Demilune, Fort Delaware, and we'll talk.

Well, maybe Fort Delaware looked into the concept and decided that "Fort Delaware's Demilune" would sound silly and its friends would laugh at it.
