Today, in my excitement for Christmas, I went looking for the man responsible for bringing presents and joy to children all around the world - and I found him! But I had some assistance along the way...
I asked an actress in the latest Bond movie, a Bird of Prey, a Doctor's assistant (and someone that looked like a smaller version of them), a Beckham, a pile of metal bits from a mattress (I don't know what I was thinking there...), a von Trapp, a Friend, a long-time American Idol judge, and a detective in the 99th Precinct of the New York City Police Department in Brooklyn.
All of them said they could help me! The question is: With these folks on-side, where did I find him?
The answer is a 10-letter geographical region.
