Duh...I missed the "literal-ness" you were referring to and YES...it is the Christmas Card Exchange...we should never take the Christ out of Christmas.
For those who don't celebrate the day...
we could always call it "The Santa Card Swap"!

Hey, I got Bob Taylor's card in the mail...thank you very much but can you tell me is this a real lighthouse? It looks like a home! I have trouble with identifying the lighthouses that are in the cards I've received so far...Shortcake's is the only one I've got recognized because it is mentioned on the back of the card...Fran? Bob?...help!
