Always go to my Grandma's in Catonsville. Nice to stay home for Thanksgiving. She's 84 years old and still going strong. We usually have 20+ extended family members, but it's quite a bit smaller this year. Big turkey, big ham, with plenty of side dishes. Mashed potatoes, green bean casserole, and some potato/cheese/butter casserole thing that tastes like heaven. Plenty of pies for dessert (apple, cherry, pumpkin, chocolate). Always a good time. We're very Italian, but we do that for Christmas. All traditional for Thanksgiving.
One semi-odd thing we do is that we eat pretty late. I know most people eat close to Noon, but we eat around 5:30. Not sure why, just always the way we've done it. Happy Thanksgiving to everyone, always a fun time of year. Hope nobody has to travel tomorrow in that crappy weather.
My family eats pretty late. We have a brunch with one side of the family early, then finish preparing dinner and take it to the other side of the family, so we don't eat until 6-6:30.
Bull Roasts are so beloved in Baltimore and so completely foreign everywhere else I've lived. Its pretty interesting.
You mean the general idea? I can't imagine most places don't have something similar, even if it involves seafood or barbecue or whatever the local specialty is.
