My sister Shavonne showed us how to Letterbox. It's like following clues and looking for treasure. When you find the box that is hidden, it has a stamp in it and a little book. You are supposed to use the stamp to stamp your own book, showing the different letterboxes you've found, and then you stamp their book with your own stamp, and write down where you live. This shows whoever hid the box how many visitors they've had and where they have come from. It's pretty fun. The kids thought of it as looking for treasure. There are Letterboxes all around the world. You should check it out. I'm sure there are some in your area. Spend an afternoon and go Letterboxing.
