We track Santa every year at http://www.norad.com/ They know when he's getting close it's time for bed. We've done it for years. The youngest is 12 and they all still want to go to that site. Especially 14 yr old DD. We also have to put our jammies on early (around 7pm) and drive around looking at all of the Christmas lights on Christmas Eve. This started when they were really little to get them to calm down and try to be tired. Now we go visit 1 house about 30 minutes away that is so decorated that they are required to have traffic patrols out to keep people moving.
