People don't usualy extensively decorate for Thanksgiving. The major tradition of Thanksgiving is the dinner. Turkey, Cranberry Sauce, Mashed Potatos, and the like. All of those things are at the store year round, with specials on Turkey and all the trimmings that are bound to be out soon. My local grocery store already has Turkey paper plates for sale, and turkeys on sale as well.
But I would like to see better Thanksgiving spirit in November. Yes, I do officialy kick off the Christmas season on the day before Thanksgiving, and the Sunday after Thanksgiving is the first Sunday of Advent. That's the day I put up all of my Christmas decorations except for the tree. I pick out a tree and have a tree trimming party on the 1st or 2nd Saturday in December.
