There's an e-mail going around about sending a holiday card to "Any Wounded Soldier" at Walter Reed Hospital. The post office WILL NOT deliver these cards. Mail has to be addressed to a particular person: Jane Smith, etc. They will either throw the cards away or return them to the sender. While looking at snopes.com about that claim, I saw that they recommended this site for anyone who wanted to mail cards to wounded military personnel. The site provides all information on how to do it and says the cards need to be sent by Dec. 10th.
