Send each partner a postcard from a location in the world that starts with a D.

Must have the place either on the front or somewhere actually printed on the postcard by the postcard publisher saying the country/ city or region/national park or national monument.

An example: if the Letter is "D" you could send a postcard from Detroit, North or South Dakota, Delaware, Denali National Park.... Deutschland etc.

Don't forget to tell a little about yourself or the place on the back.
