Naomi Bishop, 17, and Reilly Rogers, 13, take calls at the NORAD Tracks Santa Operations Center on Peterson Air Force Base Dec. 24. More than 1,200 volunteers in the 23-hour NORAD Tracks Santa operations center answered nearly 102,000 calls this year from children looking for Santa Claus (up over 20,000 from 2010). Volunteers ranged from Peterson AFB family members volunteering their time to First Lady Michelle Obama, who for the second year, answered NORAD Tracks Santa calls from Hawaii.
