A friend of mine posted this link on her FB page. As a mother of a US Marine, I am especially touched by the idea of doing this so:
When filling out your Christmas cards this year, take one card and send it to this address:
A Recovering American Soldier, c/o Walter Reed Army
Medical Center, 6900 Georgia Avenue, NW Washington, DC 20307-5001.
Please pass this on. These wonderful people have sacrificed so much.
