Rep. Gabrielle Giffords is continuing her heroic recovery after surviving the horrific shooting attack in her hometown of Tucson, Arizona, on Jan. 8, and that's something to be thankful for. Giffords helped serve Thanksgiving meals to troops and retirees stationed in Tucson Thursday. She arrived at Davis-Monthan Air Force Base wearing an apron with her nickname "Gabby" on it. She only used her left hand when she served the meals, a sign of the physical damage that she still sustains, and she was accompanied by her retired astronaut husband Mark Kelly. Giffords has been undergoing rehabilitation at a hospital in Houston.
