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 2. 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 2 will not receive a response.
