We are very involved in Letterboxing. What I would like to stress is that it requires a lot of stealth, respect and fun!
Many people hear about boxing, get some clues and run out and grab boxes. They end up leaving the boxes exposed (kids have been seen literally tossing the box back TOWARDS it's hiding spot), log books ruined and nature trampled.
Of course the majority of boxers are responsible and careful.
Before going in search of a box learn as much about boxing as you can, please read through the "rules"
About Letterboxing
including the Code of Conduct
Letterboxing Code of Conduct
And there are yahoo groups for boxing. One is called newboxers and can be very helpful in getting started. Additionally there are many local online groups so you can chat with other boxers in your area.
Letterboxing has provided my family with hours and hours and hours of fun, exercise, and togetherness. We have met wonderful people via this "hobby".
