I have made some maps with the google maps application of my sent and received cards.
Click here to see my map of my sent cards. It is funny to see that I have send two times to the same place.
Click here to see my map of my received cards. Most of my cards comes from Europe and Germany and Finland are te leaders. I haven't received a card from the same city yet and I neither have received a card from a place to which I send one.
I will try to keep my maps up to date!
