Only 90 Miles To Cuba!
I love it! Only in Key West, Florida are you closer to Havana, Cuba than you are to Miami. 
Seen here is this little seen alleyway sign signifying that it’s only 90 miles away from Cuba and yet some 157 miles away from Miami.
You can find this partially hidden sign down a small alleyway in the tourist laden area of town known as Mallory Square. There’s no alleyway name, it’s literally sandwiched between two buildings on the side of the Conch Train Depot behind a tree and park bench. This is one you’ll have to seek out… happy huntings!
