Since moving to the Mid-Atlantic region, I have often wondered why folks from West Virginia eat oysters this time of year, oysters not being native to the Appalachian Mountains. A former Baltimorean back home in West Virginia provides the history of this tradition, as well as her own personal family history. Her family served them at Christmas, but I've also met folks who included them with Thanksgiving and New year's dinner. It's so well-written that I'm just going to copy it verbatim from the email she sent me.
