The Official Rules are, "Handwrite a letter to one of our United States Military members expressing your thanks for their courage and sacrifice. Letters must be handwritten and fit on one side of an 8.5" x 11" sheet of paper."
All letters must be postmarked on or before January 31st to the following address. You also need to include your name, address, and email address on a separate sheet of paper so they have a way to contact you if you are the Grand Prize winner or one of the 4 Runner-ups. Please note that this contest is open to those under 18, however a parent permission slip must accompany the letter.
