Each year, the program delivers an average of 17,000 trees to more than 60 military bases around the country.
It is sponsored by the Christmas Spirit Foundation. A valid military ID is required. Trees are handed out one per military family and first come, first served.
This will be the ninth year that military families in San Diego's North County received the free trees.
