It's the North American Air Defense Website at www.noradsanta.org They track Santa on Christmas Eve as he flies around the world using the heat signature from Rudolph's nose!! So the children can log on and get up-to-the-minute information on where he is - even some webcam pictures from strategically placed cameras!! Apparently they send fighter jets to escort him into North American airspace, but not for long because Santa has to slow down so that the jets can keep up!!
My ds is only 10months but I can't wait until he's older and we can use as atlas to check where in the world Santa is. Actually it's quite a good learning tool too I think i.e. what country is Santa in now? Where on the globe is it? What do the people there eat, dress like etc etc?
