Here's a crazy picture of Gillian with 2 of our flat travelers from last year. The idea is to take them with you and take pictures and keep a little journal of what your life is like. We usually send pack coins, candy, flags, post cards, little American treats we find along with the traveler and his/her journal.
We are about to send back our latest flat traveler and to start looking for new adventures for our flat travelers. It helps the kids learn about other places and practice there writing (and photography skills) Very educational and so much fun! You should try it sometime.
