Follow Santa with the Official NORAD Santa Tracker and spot him as he makes his way to Washington state.
Phones are ringing nonstop at Peterson Air Force Base, headquarters of the North American Aerospace Command's annual Santa-tracking operation.
Dozens of helpers at NORAD are taking calls and tracking Santa's location on large projection screens.
NORAD Tracks Santa began in 1955 when a newspaper ad listed the wrong phone number for kids to call Santa. They wound up calling the Continental Air Defense Command, NORAD's predecessor, and a tradition was born.
