Letterboxing is much like Geocaching, except different.

It, much like Geocaching is pretty much a glorified scavenger hunt/ adventure time activity with hundred of thousands of boxes hidden around the world. The key difference is that letterboxers tend to be more old school. Each letterboxer has their own personal stamp (think ink/rubber, not postage) and each box has a "guest book" of sorts. These stamps are not the kind your grandma buys at a craft store. Most of the boxes I have found have hand-carved homemade stamps.

Usually GPS is not involved, as it is with Geocaching. Letterboxing clues can be riddles, math equations, or simply directions written in laymans terms (e.g. 50 paces east, look for a big tree). There is a website where one can look to find local boxes. Usually there is a theme to a series of boxes. Geocaching is a much newer form and gives little trinkets. Letterboxing dates back to 1854 and some of the older letter boxes from decades ago are still in commission. Each box contains a stamp (many homemade and intricately carved by hand) which the creator intended to be shared by all.

There is nothing worse than getting to a box that is supposed to have a particularly beautiful stamp and finding nothing but a bouncy ball.
