Every year the Railroad Museum in old town Sacramento does a Polar Express Train ride during the holiday season which includes an hour long ride along the river with the story being told and cookies and hot chocolate served. There is also a visit to the North Pole where Santa comes on board and delivers bells to all the children "who believe." In order to get the boys ready, we watched the movie several times (which I must admit I still didn't completely understand) and the boys happily call is the "polar conspress."
Here are the boys with their bells (ans yes, all the kids were encouraged to wear their jammies). Here is Noah on the train with our good friends the Kornaks kids Max and Alex sitting across the table from him
