The U.S. Postal Service is looking for more children in need. The service launched Operation Santa last week, which takes letters written by kids to Santa Claus and then has them adopted by charitable volunteers to fulfill the requests. A week into this year's program and so many people have given their time that the post office has already run out of letters. Letters can be sent to 123 Elf Road, North Pole, 88888 and should be postmarked by December 14th.
