If we are gonna get picky, the Southernmost point of the US is around 38 miles from my house, in one of Puerto Rico's outlying islands called 'Isla de Caja de Muertos', literally dead man's box or properly translated Casket Island.
Dead Man's Chest?
Fifteen men on a dead man's chest
Yo ho ho and a bottle of rum
Drink and the devil had done for the rest
Yo ho ho and a bottle of rum.
The mate was fixed by the bosun's pike
The bosun brained with a marlinspike
And cookey's throat was marked belike
It had been gripped by fingers ten;
And there they lay, all good dead men
Like break o'day in a boozing den
Yo ho ho and a bottle of rum.
5 more verses followed, then at the end was But one man of her crew alive, What put to sea with seventy-five.
Yo ho ho and a bottle of rum.
Robert Louis Stevenson, Treasure Island
