During December, boys and girls under 8 years old can receive a letter via CARD from jolly old Santa and his elves. Children should mail their letter to the CARD office, 545 Vallombrosa Avenue, Chico, CA 95926, no later than December 13th. A self-addressed, stamped envelope must be enclosed. The return envelope will be postmarked from the North Pole. Unfortunately, due to the amount of letters received, any letters collected after December 14th will not receive a response.
