Due to a problem with bots—seemingly thousands of them from all over the world—scanning our website for who knows what reason despite a robots.txt file that disallows it, and often slamming the website with thousands of requests in short periods of time, we now require an account to view clues on this website. It probably won’t stop all of the bots, but it will definitely slow them down!

Creating an account is free and easy, though. We won’t sell or spam your email address. We won’t even send a message to confirm your email address so you can really type anything you want for that. (Although a confirmation via email might be required in the future if bots continue to be a problem.)

Your email address, however, is how you reset your password if you forget it, so you might get yourself locked out of your account if you provide a fake one then forget it (or your password).

Sorry for the inconvenience!

Letterboxing is an intriguing “treasure hunt” style outdoor activity. Letterboxers hide small, weatherproof boxes in publicly-accessible places (like parks) and post clues to finding the box online on one of several Web sites. However, clues to finding some of the most highly-sought boxes are passed around by word of mouth.

There are about 60,000 active letterboxes listed on LbNA alone. Individual letterboxes usually contain a log book, an often hand-carved rubber stamp and occasionally contain an ink pad. Finders make an imprint of the letterbox’s stamp on their personal log book, and leave an imprint of their personal stamp on the letterbox’s logbook.
