Traveling Notebook idea

I have often wondered about the idea of a "traveling" notebook. The general concept is that a group of people send a notebook back and forth and just put random stuff in it and then send it to someone else. When the notebook is filled up, it goes back to the person who first sent it. Roberta is starting one in Italy and I thought I might start one here. The photo above is the type of notebook I have available. Alas, the paper is not fountain pen friendly, but it could still be a fun little project.

Who wants to jump in and join the adventure?
