Unfortunately a good sentiment does not equal the delivery of a holiday card to a wounded solider at Walter Reed Hospital. This rumor comes up again every year about this time and takes on a life of its own.
There is a program called Holdiay Mail for Heros sponsored by the Red Cross and Pitney Bowes which provided for the mailing of cards to soliders overseas. The deadline for those cards was December 10th.
If you see a post suggesting you send a card to “A Recovering Solider” at Walter Reed please have them read the information on Snopes.com. If you want to help a wounded solider and their family check with your local USO or make a contribution to the Fisher House Foundation or the Wounded Warrior Project.
