Each couple can bring their own favorite sub sandwich. Bring along a football and a cooler of sodas and water. Have one couple volunteer to bring a dessert, and someone else can bring some bags of chips. You will need enough “flags” so that each person has one. Play a game of flag football. It might be helpful to decide teams ahead of time so that each team wears the same color t-shirt. After the game, enjoy your subs, chips, and dessert together.
