Tens of thousands of children from the world over write to Santa at his address here in Santa Claus, Indiana, each year.

Some letters are sweet, others sad. And there are some that are, um, enthusiastic regarding the quantity of gifts requested.

And then there are some written just to check in on old Santa.

Santa's getting really busy preparing for his big night, so please make sure children's letters get here by Monday the 21st. Here's the address: Santa Claus, PO Box 1, Santa Claus IN 47579.
