We actually had "North Pole Mail Box" at the local Mall which all us kids would bring our letters to. The Mall would even have a 'special' mail carrier who would come and collect them at points during the day. Like 2pm and 5pm -- there would be a sign listing when he would arrive.
He looked like a normal mail man except he would wear Christmas colors and had elf ears. The kids would all assemble and he would tell them some kind of "Christmas-y" story, empty the mail box, and then head back for the north pole. I remember being really amazed and enchanted by the whole thing. A great memory.
Of course, once everything was all said and done all the kids would pull there parents into the toy store and bakery which the mail box was between.
They stopped doing it somewhere in between my child years and now .. I've often thought about inquiring with the mall people about make reviving it. It was a great tradition and it will get me some brownie points with the big man
"I have always thought of Christmas time, when it has come round, as a good time; a kind, forgiving, charitable time; the only time I know of, in the long calendar of the year, when men and women seem by one consent to open their shut-up hearts freely, and to think of people below them as if they really were fellow passengers to the grave, and not another race of creatures bound on other journeys." ~Charles Dickens
