I think about them and pray for them everyday.
I am an administrator at another web site, and we donate cards and a plaque each month to the families of fallen soldiers. Each month I mail the cards, and the recipient then mails to the next address, and so on. Finally, they are sent back to me. I send them with the plaque to the next of kin.
BTW, each plaque is customized - Airman, Soldier, Marine, Sailor, etc, along with their name and unit, DOD, and a very nice memorial sentiment letting the greiving know that some of us out there feel their loss and recognize the sacrifice their children/spouse/parent made.
Pretty soon, I will be making a web site dedicating solely to sending cards and plaques to the families of soldiers who have lost their lives in the name of America.
