Neal, No audio traditions per se, but a couple things I can share:
A) I often would play Christmas/holiday music on my folks' stereo in the middle of the summer ( no AC in those days), telling my Mom it made it seem "cooler".
B) for years and years I would return to the family home for holidays and bring a large Hillshire Farms beefstick (sausage). This would appear in annual photos of me and my brothers, posed for posterity. I will try and upload accompanying shots form days-gone-by. We've got photo albums full of these...
Hope all the AVAers enjoy a great holiday season.
