Pick a city anywhere in the world where you would be interested in going. Research this location and make notes. Locate pictures of this city.

Determine how many postcards you want to send. (3 is good for a start.)

Glue imagery of your location to the front (image side) of the postcard, so as to cover up the original picture. Make sure that your added material does not go beyond the edges of the original postcard.

Plan out your messages. For instance, if you are going to Australia, keep in mind that Australia's seasons are the opposite of ours. So that when we are having summer, it’s winter down there!

For the first card you may want to talk about the city you arrived in and what the temperature/weather was. (This information can be found easily online.) Example: "Weather here in Melbourne, Australia is hot and sunny. They use a different scale for measuring temperatures here. It says it is only 24 degrees, but it feels very hot. This is their summer."

Mail the cards to your Dad or friend. He can also mail cards to you from his secret journey. As your adventure continues, add to the details of your journey. You may even begin to outline a treasure hunt or riddle for the recipient to solve. Mail cards on different days so that they arrive on different days.
