Forefather's Day is celebrated in the New England area of America to commemorate when the pilgrims landed on 21 December 1620. It's particularly marked in Plymouth, Massachusetts, with ceremonies jointly led by the Old Colony Club and the Mayflower Society.
"[With oysters,] you are eating the sea, that's it, only the sensation of a gulp of seawater has been wafted out of it by some sorcery, and are on the verge of remembering you don't know what, mermaids or the sudden smell of kelp on the ebb tide or a poem you read once, something connected with the flavor of life itself."
-- Eleanor Clark (American writer. 6 July 1913 – 1996)
