I'm getting the most recent Usher CD for the soldier who requested R&B. Seems safe enough. The organizers of the letter/gift project are also still looking for gift donations to send to the 1462nd... most of the soldiers there are requesting action movies on DVD, which you can get for reasonable prices on amazon.
If anyone's interested in taking part, even if you're not able to adopt a particular soldier, please please please let me know. I'm not going to say which particular country these brave men and women are currently in suffice it to say they're out there in harm's way, and it would be completely crappy for them not to have something fun to open this holiday season.
