I just found this link at Bella Online. These are addresses for military personnel serving their country who would like to receive Holiday greetings. Some have received NO mail at all.

If it touches your heart to do so, please send a card. If you are really generous, a package. It's better late than never! Prayers are always good; they're always the right size and color.

If for any reason this link doesn't work (and for some reason I'm having trouble with links so don't be surprised) please copy and paste or type into your browser.
