We have been going to the New York City Botanical Garden's Train show the day before Thanksgiving the last three years and its amazing. There is no lines and my little children can run around and enjoy the exhibit.
Our tradition involves filming a video of us cooking and saying a bunch of inappropriate things. Then spending the digesting time editing said video.
Football, traditional thanksgiving cooking with some greek favorites mixed in and then trying to figure out how the Siberian Husky owner gets their dog to walk so nice in the dog show.
