Have you heard of letterboxing?

Ever thought of doing it with your kids?

The boys and I went this weekend, and let me tell you, I am the last person in the world who you would imagine doing something like this. But we loved it!

What is letterboxing? Basically, it's a real-life treasure hunt, filled with secrets and stamps and notebooks and hidden treasures and bugs. In other words: BOY NIRVANA.

What I really enjoyed about it is that it's a way to explore your neighborhood and discover amazing places that you never knew were there. We discovered a beautiful view of the Charles river that took our breath away -- and we'd been to that park many, many times before. We didn't know that we were supposed to go up that wooden staircase hidden between two trees -- but we did, because the clue told us to.

It's a great way to get the kids exploring, and to get mom and dad out of the comfort zone.

And the best part? It's free! All you need is a stamp, a notebook, a pen, and your spirit of adventure. Also? You need to be able to keep a secret. Can you do that? If you can, go to letterboxing.org and atlasquest.com, find some clues, grab your notebook and go out exploring.

Oh, and don't forget the kids. They'll love it too.
