Not according to the US Coast Guard Well, according to Wikipedia, not according to the US Coast Guard.
That will teach me to make guesses (I actually originally wrote "Is DL the acronym for Delaware? If so..." and then changed it).
I guess Aliceacc thought the same thing so that makes sense, but I was really confused as to why she had her stopping off in Delaware in between CT and Disneyland (of course I'm just guessing DL is Disneyland, maybe the OP does mean Delaware )
