The North American Aerospace Defense Command or NORAD use their innovative technology to track Santa beginning on Christmas Eve.  Normally NORAD is busy tracking threats, but once a year they trace the movement of Santa's sleigh as he delivers presents all over the world.

If you want to keep tabs on Santa you can visit the NORAD site and while you're there, you can step inside Santa's workshop, listen to Christmas music and play holiday games. . . Just no reindeer games, they have a job to do and need to get presents to all the girls and boys.
